The system and method for scheduling manufacturing resources

Related application

The application is in this U. S. application 09/285,286,09/285,288 that requires the inventor to submit on April 2nd, 1999,09/284,289 and 09/285,314 right of priority.

Invention field

The present invention relates to be applied to the computer system and method for resources of production scheduling, and be specifically related to determine starting material in the production run and other resources of production day expense computer system and method.Calculate (prediction) or the actual order and some preset parameter relevant that daily demand amout is based on a certain product expection by computer system and method for the present invention with the resources of production.The result of this computer system and method, that is, the plan of resources of production demand when being applied to arrangement and distributing the resources of production, provides the resources of production of enough utilizations to produce the product demand of not expecting to satisfy.

Background of invention

In producing or factory is provided with, need within a certain period of time (for example, before the shipping date of making a promise) to handle and produce order client to disparity items.For the every kind of order that does not have in those finished product inventories,, must produce this kind goods product in order to enrich customer order.For this reason, some resources of production that need use in scheduled event sequence (production procedure) lining (starting material for example, machine or production line time, workman's time and other were similar in shifts).In order effectively to utilize the resources of production of workshop and factory, and finally satisfy the diversity of customer order, the producer preferably uses a kind of system and method to dispatch the required different resource of different date and times.Scheduling of resource allows the planned resource that makes full use of of the producer.

In traditional product lot quantity production method, ordered starting material in advance and left these starting material in warehouse as raw material store.This production method is typical uses arranged the techniques of mass production, wherein based on weekly or every month plan generate arranged product.Usually based on weekly or every month finished product demand these products are produced subassembly or parts earlier.Then, these subassemblies are assembled into final finished to satisfy actual customer order, perhaps put into finished goods inventory.

To produce accessory in case dispatch, just generate work order, and based on planned production Start Date and lot-size need for the various parts of producing this accessory obtaining from the warehouse.Subassembly is the same with the production method of final finished usually.Like this, after production, these subassemblies are stored up to needs its final assembling.Because the time span of each flow process usually needs a large amount of stock's parts and finished product to satisfy customer demand unexpected or fluctuation.Thereby the production procedure of scheduling needs a large amount of spaces to store starting material, subassembly stock and finished goods inventory.And, store a large amount of like this stocks and cause the fringe cost that causes because of the out-of-date loss of starting material, subassembly and finished product and damage.

Develop computer software programs and effectively finished in the production company material planning clerk for scheduling with follow the tracks of raw materials inventory in the batch production systems, many calculating of subassembly in batches.Typically, such computer software can be based on the planned dispatching input of planner input, calculates and determines, and even can generate the starting material quantity of purchase order with the expection that need to obtain.Except the scheduling starting material, these computer softwares also can have in scheduling manufacturing resources, for example dispatch product line and in shifts the workman organize.

Also develop other dispatching methods and helped to obtain to utilize required material collection plan in the outer production run of bulk production process.The computer scheduling system of using these dispatching methods refers generally to materials demand amount plan (MRP) system.Typically, the machine that MRP dispatching system supposition is endless, workman's time and similarly, and MRP system in shifts for have certain prediction or true order-known workshop must in time determine raw-material quantity and type in specified date.

Manufacturing resource planning (MRP II) system, it is the improvement to traditional MRP system, also can be applicable to scheduling and distributes the various resources of production.MRP II system generally also uses customer order and market forecast to determine the producing predetermined required resources of production quantity of product of customer order in preset time.In MRP II system, produce a kind of product and be called as from the fate that begins to produce assembly or subassembly at first and spent and produce delivery time or production line to the final finished shipment.Owing to the long delivery cycle that the subassembly production run causes, be difficult to be reacted to as early as possible the customer order of not expecting.The queuing of each tediously long subassembly of long production delivery cycle, and get resource to the warehouse frequently come and go the long delay that will cause between production stage, so also caused in client's order and finished and loaded and transported long time period between the goods.

One of prior problem of these MRP II systems is the fine in advance production scheduling that generated, and is not easy to change.In addition, these computer software programs of using in the process generally lack the ability of adjusting scheduling when condition changing easily.If it is more flexible that production run becomes, the computer software programs that then are used to dispatch also should become more flexible.Yet in typical MRP II system, product quantity perhaps to the aggregate demand of resource, is to be provided with by master scheduling is manual, and can not adjusts easily.

Thereby, the dispatching system of having developed likely, if receive the order of some, it can it can identify when and where to run counter to resource quantity or regularly restriction, these abnormalities will be solved before their actual generations like this.Yet, relevant with product and flow process and the relation and the constraint should in these systems, accurately set up the future event that model indicates any precision.Model can comprise flow process output and probability factor, but can not indicate random occurrence, and parts, perhaps bad weather are omitted in for example equipment failure.But, must take in and preplan random occurrence, like this can excessive resource and storage capacity prevent bottleneck.Use another kind of resource instead and also can prevent bottleneck.In arbitrary situation, in time discern and respond (that is, scheduling near) for safeguarding that productive capacity is necessary.

In any production environment, timely and accurate resource planning and scheduling usually are the key factors of a success.Can determine materials demand amount in the future and comprise the potential shortage amount that the customer demand of not expecting causes because of condition changing and not expectation incident in order to the materials demand amount planning system that above-mentioned consideration strengthens.The result of success realization system reduces tank farm stock and material damage is minimized.Even yet this materials demand amount planning system also just in certain and demand plan (promptly, produce number rather than the actual customer order of product in the production system with satisfied forecast) middle performance is well, and design variation (thereby, the change of production procedure and/or raw-material type and quantity) be infrequent.

In addition, the production dirigibility of increase is particularly being produced the more than a kind of factory of product, has produced product based on productive capacity and expection and has mixed requirement to long-term MRP strategy.Dispatching method that can applications similar is controlled other commercial operations, comprises productive capacity, sells plant maintenance and factory floor scheduling.Scheduling had frequent adjustment, because will cause bigger change to many different resource demands in the little change of demand, situation, product, flow process or to their restriction.

Clearly, need a kind of system and method for improved to calculate the total daily demand amout of expection of the resources of production automatically and energy is resource-based have related parameter to adjust automatically, to adapt to user's order of not expecting or other changes (comprising the change of starting material availability) of production procedure.Also need such system, it can distribute and scheduling manufacturing resources, and the customer order of producing maximum quantity minimizes overhead simultaneously and safeguards that excessive resources bank deposits cost related.The present invention has satisfied the requirement of these and other.

Summary of the invention

Usually according to the present invention, provide to pre-determine in the production system improving one's methods and system to the daily demand amout of the resources of production.More specifically, method and system of the present invention provides resources of production demand scheme in time based on one or many actual customer orders, the prediction of following customer order, the historical data of client's shipment in the past, current finished goods inventory quantity with the preset parameter relevant with the resources of production.

The method and system can be according to whenever filling in the customer order requirement, then calculate starting material or other resources of production that when will need some, and this system and method can determine additionally that the producer need buy or produce starting material, fill-in and similar date of (based on known supplier or produce the delivery time) thus, can also plan out to satisfy other resources that the time of shipment of promising to undertake in the customer order will be used in time producing goods.Thereby management material of the present invention is with other resources and can confirm system's centralized production resource planning with order.

And, this method and system can minimize the stand-by period of being made part, the production that increases machine is used (promptly, reduce waste residue machine time) and the maximum machine dirigibility to support the method for many different product demands, distribute and scheduling manufacturing resources, for example machine time or production line utilization.For example, in the heating steps of factory flow, place the part of maximum when it is desirable to use kiln in stove at every turn.System and method of the present invention allows once by using (consumption) kiln resource more than a product.Thereby the invention provides effective manufacturing resource planning, it has supported the demand of client to many products.

This system comprise one be used to store preset parameter, about the database of customer order information and historical data.An input equipment is provided, and it allows Systems Operator's input parameter and other information.On the other hand, this input equipment can link to each other with the output of different control gears in process of production.Provide a kind of output device to generate the detailed report that resource planning distributes.When the production for scheduling distributed raw-material situation, output device can generate purchase order.On the other hand, this output device can also link to each other with the input of different control gears in the production run, perhaps even with supplier or client's order system links to each other.

It is an improved method and system that above-mentioned aspect of the present invention and other aspects are finished, and it has determined the resources of production aggregate demand of every day in several time periods of being determined by system user.For example, in very first time section, the time durations from current date (being today) to demand (that is, producing the delivery time), aggregate demand can change, even begun the product of production some.The too much product that system of the present invention utilization is minimum and maximum finished goods inventory target has been produced with supply additional product or consumption.And, have the product that postpones sign, that is, general finished product order can be before this product becomes unique step, exchange mutually in the Related product of general finished product order.

Exceeding in several cycles of requirement time durations, be called as the elasticity period, the aggregate demand of every day can determine that a number percent or fixed number increase and number percent or fixed number reduce (this number percent or several can be the same or different) and change by each product user.Can there be a different number percent in each cycle, and for example, can there be different fates every period of one-period, however in one-period all days all use the same elasticity number percent that this should the cycle.This number percent or fixed number are represented to make the plussage of these resources spendable in order to satisfy client's product order of a predetermined level is exceeded to every kind of plan.Generated available volume of resources during the elasticity, this capacity is ordered the trend direction along continuous client and is moved, and it is by comprising one or more current turnout, and the weight factor that following order is predicted and the client loaded and transported history is in the past determined in interior numeral.

In case determined the amount during elasticity, system generate a plan order starting material and scheduling enough foundation add other resources of production of total expectation demand of demand during the elasticity.System has set up the dirigibility of the customer order that can satisfy elastic region upper limit quantification like this.

Exceed the order of required amount time durations if receive portion, and this order is bigger than the demand and the additional flexibility demand (being called the high resiliency amount) on this date of total prediction, native system and method will calculate once more above the demand time durations and before this orders the date aggregate demand of all fates, attempt is filled up the necessary aggregate demand amount of order with what is called smoothing process.In the resources of production demand of measuring during calculating reaches elasticity, system uses a kind of algorithm, and it comes adjustment amount to prevent arbitrary day aggregate demand above this day plan available raw materials amount and other mode.Thereby, by the smoothing of fate in early stage, even only flexible excessive stock number of the producer and quantity of material also can satisfy in client's order of ordering the high resiliency amount of not expecting day that surpasses.

Also provide the difference during production line that customer status and finished product are replenished the intermediate report of ordering at improvement system and method for the present invention.If problem has taken place, can recognize at once and report, system can take action and deal with problems like this, such as passing through from other deposits, for example from noncommittal customer order or market order, promise to undertake and can utilize number, finished goods inventory or finished product to replenish order, come the consumption of natural resource demand.

Method and system of the present invention has also solved various resource management problem.The resource that can manage comprises starting material, machine or production line time, man-hour, other labours, space, the energy or any other limitations affect are accepted the amount of deliver goods and Service Order ability in shifts.

For example, in building industry, the scheduling utilization of resource can include the build labourer of general or special expertise, various individual event tasks or multipurpose plant and materials demand amount; In forwarding business, effectively utilize the motor vehicle of conveying people, material and facility between special or general a plurality of positions; In health care, can dispatch and use sick bed, operating room, general or special office worker and fixing or mobile device.Other use of system and method for the present invention, for those can understand specific embodiment described here people will and easily see.

Accordingly, a purpose of this invention provides a kind of system and method, be used for plan, scheduling is used for satisfying the customer order of not expecting with the distribution resources of production with maximization production dirigibility and minimizes the relevant expense of keeping the excessive ability of this type of resource with other of inventory cost simultaneously.

The preferred embodiment explanation

Can well understand different specific embodiment of the present invention and example and their advantage referring to figs. 1 to Fig. 8 v, similar numeral is used to represent similar and corresponding part among the different figure.Following explanation is providing the present invention in the announcement General Principle of the present invention to be described also in detail.

The next example of system and method for the present invention is the daily demand amout administrative model.Fig. 1 has described schematically showing according to of the present invention day administrative model.The production run delivery time, i.e. streamline 100 expressions are assembled to the customer order time necessary amount of producing from starting material.Distal point at streamline 100 is the demand time durations, DTF102.The product that only can be used for production line 100 by the resources of production amount of DTF102.In general, scheduling is gone forward side by side into the resources of production amount or the aggregate demand 103 of streamline 100 by DTF102, will equate with bigger that in premeasuring 104 or the actual every day customer order 105.Every day, rate 107 was in the resources of production, consumption rate, and rate every day of establishing the DTF102 place equals aggregate demand 103.Difference between premeasuring 104 and actual customer order 105 is the admissible off-the-shelf amount ATP114 that can be used for filling other customer orders.

In order to ensure satisfying premeasuring 104 and/or the resources of production of the actual customer order 105 that fluctuates, accumulated the deposit 108 of the resources of production.Deposit 108 should be to be enough to provide premeasuring 104 and actual customer order 105, and should make the trucking costs of excess on hand and other resources of production minimum.A kind of technology of known plan deposit 108 comprises and is provided with during the elasticity, and expression surpasses and is lower than rate 107 the number percent or amount every day that can satisfy customer order during the elasticity.

The method of this known plan elasticity quantity depends in rate current every day of demand time durations, has seen that this can cause the acutely fluctuation up and down between the sky, and fluctuation has unfavorable result for the planned production resource utilization.The actual subscription rate of any specific products is very important, and random variation one monthly average and the season of nature on average are predictable, but mean value was very different therewith in arbitrary day.In system and method for the present invention, during the elasticity be one based on composite number it have pair streamline, client order premeasuring and shipment in the past historical every day rate one or more average every day rate weighting factor.Thereby the direction that elastic region connects the continuous trend of demand moves, and is not random variation or unusual every day.Be easy to adjust to time-current production, prediction in the future, in the past historical-or wherein one or more groups the most relevant synthetic top-priority that.

Typically, used three flex time sections, wherein each time period is illustrated in some days above DTF102, and elasticity quantity all increased every period.As shown in Figure 1, flex time section 1109 prolongs six days 5% amount of elasticity.Flex time section 2110 prolongs eight days 10% amount of elasticity.Flex time section 3111 has prolonged ten days 20% amount of elasticity.But thereby can be in six days of DTF102 order scheduling and surpass current every day of rate 107 5% the available resources of production to satisfy the client.Equally, can the fortnight of DTF102 in, can dispatch and surpass current every day of rate 107 10% the available resources of production.At last, can in two fortnights of DTF102, can dispatch and surpass current every day of rate 107 20% the available resources of production.

Thereby, calculate the aggregate demand 103 of every day to certain given living resources by time period during the program user input flexibility 109,110 and 111 backs.At current date, today 115, between DTF102, general aggregate demand can not change, because by this turnout production and will finish production in certain fate.During during the elasticity 109,110 and 111, the aggregate demand 103 of every day can become, for example the number percent of determining because of product user.Different number percent is arranged during each elasticity, and during each elasticity different fates can be arranged, however all days in during elasticity the elasticity number percent in generally all using during this.

In case determined during elasticity the amount in 109,110 and 111, native system produces the starting material plan and other resources of production is generated to be enough to set up and adds that amount is at the daily demand amout of interior expectation demand during the elasticity.If receive order above the DTF102 date, and this order is bigger than the proof resilience demand of that day, and native system will recomputate DTF102 tries hard to scheduling and can utilize the resources of production to produce to smooth demand process with what is called and fill up the necessary aggregate demand of order to ordering before the date aggregate demand of these days later on.。

Also there is another problem at known system and method during utilizing elasticity.If it is improper to be provided with during the elasticity, may produce undesired finished goods inventory.For addressing this problem,, replenish and order considerably beyond conservative finished goods inventory producing finished product if the order rate of certain given product is lower than rate every day.Say again, if the order rate height of certain given product has no idea to satisfy order finished goods inventory in streamline in known one-tenth system and method.

System and method of the present invention has utilized the smoothing process, this process comprise a computing machine and with a kind of algorithm of software programming to the resources of production demand of a kind of product smoothing to the time.The smoothing process variable receives customer order from typical order management system, and can distribute and dispatch the required resources of production demand of production customer order.Different order strategies also promptly consumes strategy, needs different algorithm steps to determine the finishing date of product and the product volume that can finish on any given date.

With the very big customer in response demand of forecast consumption strategy, the minimum stock who keeps the resources of production simultaneously.As described in Figure 1, with 109,110 and 111 providing starting material deposit 108 during the outer elasticity of DTF102 to satisfy the demand bigger than prediction.Because this consumes strategy, replenish order for the target of production minimum finished goods inventory has generated finished product, and this finished goods inventory is used for arriving demand time durations 102 at customer order the situation of (that is, in less than this finished product institute spended time of production).

With reference to figure 2 algorithm steps of forecast consumption strategy has been described, has wherein required in DTF102, to set up the client and set up and produce target date RBCD200.In the first step 21, finished product replenishes order FGO101 115 (from right to left) from RBCD200 to today will be consumed in 100 li on streamline continuously, and it may cause finished goods inventory maximum target FGI Max 201 to be exceeded.That is, calculate current finished goods inventory, FGI202 adds that FGO101 in the streamline and consumption cause that FGI202 adds FGO101's and greater than the FGO101 of FGI Max 201.Next step 22, then consumed the FGI202 that surpasses FGI Max 201.Next step 23, continuous consumption (from right to left) from RBCD200 to today 115 in streamline remaining FGO101.Next step 24, consumed deserved in the past FGO203.Next step 25, the market order 207 of the unappropriated customer order 206 of 115 (from right to left) continuous consumption and any scheduling from RBCD200 to today.Next step 26, consumed remaining FGI202.

If also the amount of satisfying the demands has not generated RBCD and run counter to, then tell to make the user can not in promise date, satisfy customer order.System can select from left to right to move the order date of promising to undertake, and the unappropriated customer order of continuous consumption and market order are up to satisfying whole demand.System is to the user report order target date then.

Fig. 3 has shown the algorithm steps of RBCD200 outside requiring time durations 102.In the first step 31,115 (from right to left) continuous consumption will cause the FGO101 in the streamline 100 that FGI Max 201 is exceeded from RBCD200 to today.That is, calculating current FGI202 adds FGO101 and consumes and will cause FGI202 and FGO101's and greater than the FGO101 of FGI Max 201.Next step 32, then consume the FGI202 that surpasses FGIMax 201.Next step 33, (from right to left) continuous consumption ATP114 from RBCD200 to DTF102.Next step 34,115 (from right to left) continuous consumption will cause the FGO101 of the streamline 100 of FGI Min 204 in being exceeded from RBCD200 to today.Next step 35, consume deserved in the past FGO203.Next step 36, from RBCD200 to today the unappropriated client of 115 (from right to left) continuous consumption order 206 and the market of any scheduling order 207.Next step 37, consume to surpass the FGI202 of FGIMin 204.

If the amount of satisfying the demands not also, in step 38, from RBCD200 to demand time durations 102 (from right to left) continuous consumption available high resiliency amount.Available high resiliency amount is the maximum of planned production resource.As described in reference to figure 1, they by any given elasticity during amount of elasticity determine.Next step 39,100 li remaining FGO101 of 115 (from right to left) continuous consumption streamline from DTF102 to today.Next step 40, consume remaining FGI202.

If also the amount of satisfying the demands has not generated RBCD and run counter to, then tell the user can not in promise date, satisfy customer order.In step 41, system can from left to right move the order date of promising to undertake, and the unappropriated customer order 206 of continuous consumption, market order 207, ATP114 and high resiliency amount are up to satisfying whole demand.The order target date to the user report revision is followed by system.

Usually the sales forecast of determining in season with predicting strategy substantially exceeds in the production plant of productive capacity, handles seasonal straight line and rises.When in the demand time durations, receiving a large amount of order, also use this strategy.In these situations, outside DTF102, do not use during the elasticity, so only planned the resources of production of enough production forecast amounts 104.And, generate the FGO101 that satisfies minimum FGI target 204.

With reference to the algorithm steps of figure 4 explanation RBCD200 in requiring time durations 102.In the first step 42,115 (from right to left) continuous consumption will cause the FGO101 of the streamline 100 that FGI Max 201 is exceeded from RBCD200 to today.That is, calculating current FGI202 adds the FGO101 in the streamline and consumes and will cause FGI202 and FGO101's and greater than the FGO101 of FGI Max 201.Next step 43, consume to surpass the FGI202 of FGI Max 201.Next step 44, continuous consumption is 115 (from right to left) remaining FGO101 in streamline from RBCD200 to today.Next step 45, consume deserved in the past FGO203.Next step 46, the unappropriated client of 115 (from being shifted to the right to a left side) continuous consumption orders and the market order of any scheduling from RBCD200 to today.Next step 47, consumed remaining FGI202.

If also the amount of satisfying the demands has not been run counter to RBCD, then tell to make the user can not in promise date, satisfy customer order.In step 48, system can from left to right move the order date of promising to undertake, and the unappropriated customer order of continuous consumption and market order are up to satisfying whole demand.System is then to the user report order target date.

Fig. 5 has shown the algorithm steps of RBCD200 outside requiring time durations 102.In the first step 51,115 (from right to left) continuous consumption will cause the FGO101 of the streamline 100 that FGI Max 201 is exceeded from RBCD 200 to today.That is, calculating current FGI202 adds the FGO101 in the streamline and consumes and will cause FGI202 and FGO101's and greater than the FGO101 of FGI Max 201.Next step 52, then consume the FGI202 that surpasses FGI Max 201.Next step 53, from RBCD200 to demand time durations 102 (from right to left) continuous consumption ATP114.Next step 54, the FGO101 of 100 li on 115 (from right to left) continuous consumption streamline from RBCD200 to today.Next step 55, consume deserved in the past FGO203.Next step 56, from RBCD200 to today the unappropriated client of 115 (from right to left) continuous consumption order 206 and the market of any scheduling order 207.Next step 57, consumed remaining FGI202.

If also the amount of satisfying the demands has not been run counter to RBCD, then tell the user can not in promise date, satisfy customer order.In step 58, system can from left to right move the order date of promising to undertake, and the unappropriated customer order 206 of continuous consumption, market order 207 and ATP114 are up to satisfying whole demand.The order target date to the user report revision is followed by system.

The actual subscription application of policies is in a small amount of product of fragmentary demand.In the case, premeasuring 104 can not be suitable for.Outside DTF102, do not exist during the elasticity.Do not plan the FGO101 and the FG1202 of 100 li on streamline; Only place an order (in the situation of FGO101) and if then they just exist when cancelling this order in (in the situation of FGI202) in the DTF102 as the client.

Algorithm steps with reference to figure 6 explanation actual subscription strategies.In the first step 61, if there is FGI202 just to be consumed.Next step 62, the FGO101 of 115 (from right to left) continuous consumption streamline 100 from DTF102 to today.Next step 63, from RBCD200 to today the client of 115 (from right to left) continuous consumption unallocated (i.e. cancellation) order 206 and any market order 207.

If the amount of satisfying the demands not, and RBCD is less than producing the delivery time MLT205, the required time of other resources of production of production customer order that perhaps accumulates all raw material and scheduling usefulness, run counter to RBCD, then told user person's order before promise date, not satisfy.In step 64, system can from left to right move the order date of promising to undertake, and the unappropriated customer order of continuous consumption and market order are up to satisfying whole demand or up to having crossed MLT205.System is then to the user report order target date.

Narrated the option of several enhancing smoothing processes.It allows system and method for the present invention to adapt to the various conditions that may occur in any given production run.These modifications comprise promise can utilize series, package quantity, smoothing time left side boundary, fixing and general finished product order series.

Be used for promising to undertake series: this part belongs to one " ATP series " and can share each other premeasuring.It provides a kind of dirigibility of production customer demand, and this demand is not predicted specific products corresponding to another product consumption requirements from ATP series.Like this, can reduce the starting material amount that is retained in for any independent product on hand.Here it is the present invention is based on the administrative model of demand, shows as the reduction of measuring during product elasticity in the ATP series.Typically, algorithm will be revised as the ATP that at first consumes institute's order and then other part consumption sharing A TP on the same day in the ATP series.

Packing Unit: some customer requirement orders are with many times of amount shipments of certain parcel loading amount.Like this, revised the consumption rule of this algorithm.Consumption in given certain day any classification is the multiple of this Packing Unit like this.

Smoothing time left side boundary: the ordering products that smoothing time left side boundary prevents to have RBCD is near will be away from the FGO101 and the ATP114 that consume 100 li of FGI202, streamline in the time period of DTF102.Smoothing time left side boundary length is to determine on the date that after this smoothing takes place from the target date skew of customer requirement.If left side boundary date smoothing time outside DTF102, does not then then consume to whatever between the DTF102 on the left side on left side boundary date smoothing time.If left side boundary date smoothing time then adapts to the normal consumption rule in DTF102.

Limit: limit permission production discrete cell and be imparted to the particular customer order.A kind of hard closed indent will have a specific ID unit (may be a physical tags, mark or other diacritic features) to each parts; The association of unit is hard and binding.When producing smoothing, these parts can not be assigned to any other customer order.This will obviously reduce the amount of the available resources of production outside DTF102.Can specify soft closed indent, and limit for any soft qualification customer order again.Soft fixedly order meets the smoothing rule of logic.

General finished product order series: on the just left side of DTF102 one time window is arranged, wherein allow the general FGO101 that considers several finished products.These products are tradable in DTF102, up to certain special process, and for example punching press or spraying.This new time durations, perhaps general window of opportunity is general finished product order time boundary.In case FGO101 leaves this window, just disappeared from the chance of other finished product consumption requirements amounts.Yet in during the general finished product order time, any finished product that general finished product is ordered series can consume this finished product.

In addition, when reference requirement amount event horizon and elastic region one day time durations at interval is discussed, system and method for the present invention allows to use slightly little or big slightly time durations interval.Like this, for example, can be divided into class Three every day, and be the separately consumption and the distribution of the means of production of each class.

To choose enhancing wantonly together with above-mentioned can be used as below, provide an example of system and method for the present invention.With reference to figure 7a, the first according to the process flow diagram of the method step of the algorithm that uses of the specific embodiment of the invention has been described.When the new customer order that receives a kind of product, the method starts from 300.In the quantity of square frame 302 places inputs order and set up demand to the various resources of production.The product of ordering in this situation can be the finished product that the client orders, or must be by ordering the subassembly that the client produces finished product.At square frame 302 input product quantities can be that the user directly imports at workstation 304, perhaps can determine that the order endorsement system 306 of many different product quantity of given customer order receives in enterprise.

The method is then retrieved the order strategy of this product in the step 332 of input order strategy.The user person of system orders strategy and is stored in system database 320 for each product is provided with.Another kind, the user can select a kind of order strategy and at workstation 304 directly with its input.Whether the method then uses the forecast consumption strategy at 308 decision products.Do not use the forecast consumption strategy as fruit product, whether the method uses predicting strategy at 310 decision products.Do not use predicting strategy as fruit product, whether the method uses actual order strategy at 312 decision products.Do not use actual order strategy as fruit product, then this product does not use any available admitted order strategy and at step 314 reporting errors.Certainly will recognize that the method can carry out determining step 308,310 and 312 and at another embodiment with any order, use which order strategy such as the judgement product that uses the CASE statement.

If this product uses actual order strategy, the method is transferred to 316 A.Perhaps, if this product uses predicting strategy, the method is transferred to 318 B.Otherwise if do not report any mistake, then this product uses the forecast consumption strategy, and the method is transferred to the RBCD at square frame 322 input orders.RBCD is the date of product order entry system, and generally it is set to than the product bigger fate of (that is, producing) fate of can delivering in production line flowing water 100.For example, if the customer requirement product was delivered in 20 days, and produce this product and will spend 4 days (streamline 100 equals 4 days), RBCD is set to 16 days.This date can be by the user in workstation 304 inputs, and perhaps preferable obtains from order endorsement system 306.

The method is then retrieved the DTF of this product in the step of input DTF330.For each product is provided with DTF and stores this DTF in database 320.Another kind, the user can determine DTF and directly import at workstation 304.The method then at 324 decision RBCD whether in DTF.If RBCD not in DTF, RBCD outside DTF then the method transfer to 326 C.Otherwise RBCD is in DTF and the method is then replenished the step of order and finished goods inventory maximum target (FGImax) at the current finished product of square frame 327 input current finished goods inventories (FGI), streamline (FGOpipe) lining.What the method was preferable retrieves these information from database 320, and native system can keep the renewal to 320 li information of database.

The method then determines whether to exist the excessive FGO in streamline that will cause FGImax to be exceeded in process 328.Process 328 comprise calculate FGI add FGOpipe and with FGImax relatively:

FGI+FGOpipe＞FGImax

Once more, be preferably in 320 li values of safeguarding FGI and FGOpipe of database.Another kind, the user directly imports these data at workstation 304.The method is estimated the excessive FGO that whether has from process 328 334.If have, consume these excessive FGO and the method at square frame 336 and determine 338 whether resources of production demands have satisfied and finish customer order.If can satisfy then the method is finished 340 and finished.

If the amount of satisfying the demands does not perhaps have excessive FGO from 334, then the method determines whether to have excessive FGI in process 342.Process 342 comprises the comparison of FGI and FGImax:

FGI＞FGImax

Value at square frame 327 retrieval FGI and FGImax.Whether the method evaluation has excessive FGI 344.If have, determine 348 whether resources of production demands satisfy customer order at square frame 346 these excessive FGO of consumption and the method.If satisfy, then the method finishes 340.

If do not satisfy, perhaps in 344, there is not excessive FGO, the method is at the D that transfers to 350.Shown in 352 D among Fig. 7 b.The method then determines 354 li whether remaining FGOpipe is arranged in process.Value at square frame 327 retrieval FGOpipe.The method evaluation is at the 356 residual FGOpipe that whether have from process 354.If have, determining 360 to determine whether resources of production demands satisfy customer order at square frame 358 these excessive FGOpipe of consumption and the method.If satisfy, the method finishes 340.

If do not satisfy, if perhaps do not have residual F GOpipe from 356, the method is then carried out the input current orders of finished product in the past (FGOpast) at square frame 362.Preferable in 320 li values of safeguarding FGOpast of database.The method has then determined whether excessive FGOpast in process 364.The method is estimated the residual FGOpast that whether has from process 364 366.If have, determining 370 to determine whether resources of production demands have satisfied customer order at square frame 368 these residual FGOpast of consumption and the method.If satisfy, the method finishes 340.

If the amount of satisfying the demands not, if perhaps not from determining 366 residual FGOpast, the method is then carried out the step of the market order (MO) of input unallocated customer orders (uCO) and any planning at square frame 372.Preferable in 320 li values of safeguarding uCO and MO of database.The method has then determined whether excessive uCO and MO in process 374.The method is determining whether 376 assessments have uCO and the MO from process 374.If have, consume those uCO and MO and the method at square frame 378 and determining 380 to determine whether to satisfy and finish the required resources of production demand of customer order.If satisfied this demand, the method is finishing 340 end.

If demand does not satisfy, if perhaps do not have uCO and MO from 376, the method then determines 382 li whether remaining FGI is arranged in process.The value of square frame 327 retrieval FGI in Fig. 7 a.Whether the method evaluation has FGI 384.If have, determine 388 whether resources of production demands satisfy customer order at square frame 386 these FGI of consumption and the method.If satisfied this demand, the method is transferred to 402 F, and F404 finishes 340.

If the amount of satisfying the demands not, if perhaps do not have FGI from 384, the method generates RBCD and runs counter to 390, and the demand of the resources of production of announcement can not satisfy customer order.This system and method for the present invention is had the ability to determine to have at which day and is satisfied the required available resources of production demand of customer order.So which can fill up user's order at (i.e. best date) at.In the case, each product records a best date switch, if when this switch is opened, tells system and method for the present invention to determine to fill up first date of customer order.

The method is retrieved best date on off states at the best date switch square frame 392 of input, and determines the state of these switches in process 394.Whether the method is being opened at the best date switches of 396 assessments, and if do not open, the method is transferred to 406 F and part F and is finished 340.If opening at 396 best date switches, the method was the back mobile RBCD of square frame 398 one day.Square frame 398 increases RBCD one day.The method is then transferred to 400 E.E shows in Fig. 7 a, and the E control of shifting the method gets back to 324 to determine that RBCD is whether in DTF.

In the RBCD situation in DTF not, the method is from 326 C that transfer to 408 in Fig. 7 c.Then the method is carried out input FGI, FGOpipe, FGImax and finished goods inventory minimum target (FGImin) at square frame 410.What the method was preferable retrieves these information from database 320.

The method then determines whether to exist the excessive FGO that will cause in the streamline that FGImax is exceeded in process 412.Process 412 comprise calculate FGI add FGOpipe and will with FGImax relatively:

If the amount of satisfying the demands is arranged, if perhaps do not have uCO and MO from 464, the method has then determined whether greater than FGImin residual F GI 470 li of processes.Retrieved the value of FGI and FGImin at square frame 410.The method is assessed the FGI that whether has greater than FGImin 472.If have, whether FGI and the method for consuming greater than FGImin at square frame 474 satisfy customer order in 476 definite resources of production demands.If satisfy, the method is transferred to 478 F, and F404 finishes 340.

If the amount of satisfying the demands not, if perhaps from 472 not greater than the FGI of FGImin, the method is then transferred to 480 H and section H 482 and is shifted the elastomeric value of square frames 484 inputs.Be preferably 320 li of databases and safeguard elastomeric values (not showing) or can be by the user in workstation 340 (not showing) input.The method then determines whether excessive high resiliency in process 486.The method is assessed the high resiliency that whether has from process 486 488.If have, determine 492 whether resources of production demands satisfy customer order at this residue high resiliency of square frame 490 consumption and the method.If satisfy, the method is transferred to 494 G and part G440 and is finished 340.

If the amount of satisfying the demands not, if perhaps there is not high resiliency in 488, the method has then determined whether remaining FGOpipe for 496 li in process.Retrieved the value of FGOpipe at square frame 410.The method evaluation is at the 498 residual F GOpipe that whether have from process 496.If have, determine 502 whether resources of production demands satisfy customer order at square frame 500 these excessive FGOpipe of consumption and the method.If satisfy, the method is transferred to 504 G and G440 and is finished 340.

If the amount of satisfying the demands not, if perhaps there is not FGOpipe in 498, the method is transferred to 506 I.Shown I508 in Fig. 7 b, I rotates back into process 382 with control and determines residual F GI and continuation therefrom.

When the order strategy from Fig. 7 a square frame 332 is the situation of predicting strategy, 318 508Bs that transfer in Fig. 7 d of the method from Fig. 7 a.Then the method can equal 0 and then 512 J514 that transfer among Fig. 7 a from Fig. 7 d during square frame 510 is provided with elasticity.J514 rotates back into square frame 322 with control, input RBCD and continuation therefrom.

When the order strategy from the square frame 332 of Fig. 7 a is the situation of actual order strategy, 316 A516s that transfer in Fig. 7 e of the method from Fig. 7 a.Then the method can during square frame 518 is provided with elasticity, equal 0 and premeasuring equal 0 and then the transferase 45 20 from Fig. 7 e transfer to J514 among Fig. 7 a.J514 rotates back into square frame 322 with control, input RBCD and continuation therefrom.

Certainly, should be noted that the accurate order that resources of production demand is consumed can change in not departing from scope of the present invention.For example, do not have the product of enough shelf lifes, or during other products that rot easily, expectation replenishes order and preferentially consumes any finished goods inventory that surpasses the finished goods inventory minimum target prior to finished product in streamline in the manufacturing.With reference to figure 3, can direct execution in step 37 after step 32 and before the step 34.This will make system and method tendency of the present invention keep the finished goods inventory minimum target.Thereby the goods that rots often can be retained on stock's shelf easily.

Should also be noted that the situation that belongs to ATP series in specific features, can revise the method, be convenient to before square frame 434 and process 442, to consume the miscellaneous part consumption ATP from ATP series after any excessive ATP (if there is) in the process 430 of Fig. 7 c.And the method consumes after any excessive high resiliency (if there is) before can also being modified in square frame 490 and process 442, the available high resiliency of sharing from the consumption of ATP series miscellaneous part in the process 486 of Fig. 7 c.

Rate is several days a mathematical mean because system and method for the present invention is determined synthetic every day, and it comprises prediction and historical element in the future in the past, can suppress the upper and lower big ups and downs of actual every day of rate and can eliminate the artificial interference of rate every day.Elasticity volume is only with demand trend, historical pattern, perhaps some impulsions of changing of prediction and changing.Extra elasticity volume is only with demand trend, and historical pattern predicts that perhaps some impulsion amounts that change are just available.Thereby supplier has seen it not being the less changeableness of an actual demand amount trend part and the direction that the actual demand amount is provided that there is the reliable reflection of more predictabilitys in system.Which the material planning person can determine more important by the weighting of the mean value of adjusting composition, streamline rate, pre-quantitation or historical data.And the observation of time frame can be arranged to have nothing in common with each other in every month.

To Fig. 8 v, shown an example of the arithmetic result that is applied to not expect customer order according to a particular embodiment of the invention with reference to figure 8a.Fig. 8 a has described and has worked as precondition, before the extra client order of today and reception product.

So shown in the example, producing the delivery time is six days, and has during three each elasticity of three days by a definite date, and 10%, 20% and 30% amount of elasticity is arranged respectively during each.The product of 20 units and 10 FGOpast836 of unit of finished product order are in the past arranged in finished goods inventory FGI834.Rate every day of today 802 832 is 100.That is, will produce the product of 100 units today.In these 100 units, 90 distribute to customer order 838 and remaining 10 units to be current finished products in the streamline replenish order FGOpipe840.

Shown in whole during the prediction of (15 days) be 100 unit products every day.At the actual customer order 838 that has shown product every day in the works.In this example, actual customer order is lower than pre-quantitation, so rate every day in the streamline 832 is set to premeasuring 100.Surpass those days of pre-quantitation in client's quantity ordered, will every day rate 832 be set to client's lot-size.

The demand of current planning, demand 844 in during the elasticity, also is set to the big person between actual client's lot-size 838 and the pre-quantitation.The quantity available that allows, ATP842 is the poor of demand 844 and actual client's lot-size 838.

The finished product of having produced and not distributed to customer order replenishes order and can distribute to finished goods inventory except that satisfying new customer order.

Now, at the new order of 100 unit products of shipment in the 9th day with to 50 unit products of shipment in the 4th day.This algorithm is checked the request the earliest of setting up the target date, the 4th day, at first, determines whether to satisfy this requirement of product.This algorithm at first consumes 10 FGOpipe of unit of the 4th day 808 and forwards them to client's lot-size 838.With reference to figure 8b.

Then, this algorithm consumes 10 units of FGOpast836, and 10 FGOpipe of unit (this also may be thought of as FGOpipe in this context) that consume today 802 and can use and transfer them to client's lot-size 838, with reference to figure 8c, for satisfy the 4th day order also needs produce 20 units.

Then, this algorithm consumes the FGOpipe (from right to left) of next day among the available FGOpipe, in this example, with the FGOpipe of 20 units of the 3rd day 806, stays 10 units, is client's lot-size 838, satisfies the 4th day demand.With reference to figure 8d.

Algorithm assigns is at the customer order of 100 units of the 9th day now.Algorithm at first consumes 30 unit products from the 9th day 818 ATP842.With reference to figure 8e.

Then, the ATP842 that this algorithm moves up into a day (from right to left) and consumes at 20 units of the 8th day 816, then algorithm shift-in one day and consume 10 ATP842 of unit again at the 7th day 814.With reference to figure 8f.Also need to distribute 40 unit product demands.

Then, this algorithm is shift-in several days again, crosses the demand time durations, and DTF102 is up to finding stupefied available FGOpipe840.In this example, consume 40 unit products from the 5th day 810 FGOpipe840, stay 10 a units product, and satisfy the product demand of the 9th day customer order.With reference to figure 8g.

Now, 100 unit new orders will be shipment in the 9th day.Do not stay ATP842 between the 9th day 818 and the DTF102.Thereby 40 FGOpipe of unit that this algorithm is checked FGOpipe and consumed the 2nd day 804, the 3 days 806 and the 5th days 810 also will distribute 60 units with reference to figure 8h.

This algorithm then consumes the FGI834 that surpasses the finished goods inventory minimum target, in this example, is 0 to have consumed 20 all FGI834 of unit so minimize Target Setting.With reference to figure 8i.

Algorithm then consumes high resiliency 846, shifts to DTF102 since the 9th day 818.Like this, client's lot-size 838 of the 7th day 814, the 8 days 816 and the 9th days 818 is increased to 110.With reference to figure 8j.Notice that the demand of these days is increased to 100, reflecting to increase resource requirement.

Also need to distribute the finished product demand of 10 units.Yet available never again resource satisfies this demand under current plan.If the best date switch of this product cuts out, then system runs counter to user report RBCD.On the other hand, if the best date switch of this product is being opened, then this algorithm checks that next available ATP842 (from left to right) consumes 10 ATP842 of unit of the 10th day 820 in this example.With reference to figure 8k.Because this order demand satisfies now, can report the best date, the 10th day, and change in the prompting customer order.

For this example, suppose that best date switch opening.Received 250 unit new orders at the 14th day.At first, consume the ATP842 of 80 units of the 14th day.Shift to DTF102, consumed the ATP842 of 70 units from the 13rd day 826, consumed the ATP842 of 60 units from the 12nd day 824 and consumed the ATP842 of 40 units from the 11st day 822, stayed 10 ATP842 of unit at the 11st day 822 and satisfied the 14th day new order demand.With reference to Figure 81.

Notice that system and method for the present invention has satisfied customer order near RBCD, has stayed ATP and FGOpipe near today as much as possible.Thereby early customer order can also satisfy.

In next day, became today on the 2nd day.Because demand 844 was increased to 110 in the 7th day 814, every day rate 832 to be set at the 6th day 812 now be 110.With reference to figure 8m.Other day from right to left, and new had be added in this plan in the 15th day 830 of 0 customer order.

Notice that be based on the every day rate to whole streamline and prediction in the future and historical data average in the past because with target rate every day amount of elasticity is set, typical amount is change not.Yet if whole streamline rate every day has been increased, amount of elasticity also will increase.Like this, amount of elasticity is not a flip-flop, but only corresponding on the rise.

Continue to come order.Now, receive order at 125 units of the 15th day.At first consume 100 ATP842 of unit at the 15th day 830.With reference to figure 8n.Also need 25 units.

Then, consume the ATP842 of next 25 units of the 14th day 828 that enter.With reference to figure 8o.The 15th day order demand has satisfied.

In next day, became today on the 2nd day.With reference to figure 8p.Continuing order has.Equally, all dates move from right to left and have increased new the 15th day 830.Now, receive order at 125 units of the 15th day.At first, at first consume 100 ATP842 of unit of the 15th day 830.Also need 25 units.Then, consuming the ATP842 of 25 units in the next sky that available ATP is arranged that enters, is the 13rd day 826 in this example.With reference to figure 8q.The 15th day order demand has satisfied.

In next day, became today on the 2nd day.With reference to figure 8r.Order continues to arrive.Now, receive order at 125 units of the 15th day.At first, consume 100 ATP842 of unit at the 15th day 830.Also need 25 units.Then, consuming the ATP842 of 25 units in the next sky that available ATP arranged, is the 12nd day 824 in this example.With reference to figure 8s.The 15th day order demand has satisfied.

In next day, became today on the 2nd day.With reference to figure 8t.Notice that owing to crossed DTF in the 7th day 814, actual order measures 848 during being less than low elasticity.Replenish order so produce the finished product of schedulable 20 units.With the method, the resources of production amount that is used for production run is not to change significantly and the actual least resource amount of using plan.

Order continues to arrive.Now, receive order at 125 units of the 15th day.The ATP842 of 100 units of the 15th day 830 of Xiao Haoing at first.Also stay the demand of 50 units.Then, consume the ATP842 in the next sky that available ATP is arranged that enters, in this example, 15 units of the 11st day 824 and 10 units of the 7th day 814.With reference to figure 8u.Also stay the demand of 25 units.

Because DTF102 do not have ATP842 outward again, and do not have available FGOpast836 and FGI834 yet, this algorithm shift-in (from right to left) is up to there being first day of available FGOpipe840, in this example in, having first day of available FGOpipe840 is the 6th day 812.Consume those 20 units and transfer it to client's lot-size 838.Also stay the demand of 5 units.Thereby this algorithm shifts out (from left to right) up to first day that available amount of elasticity is arranged, and in this example, having first day of available amount of elasticity is the 7th day 814.Client's lot-size 838 of the 7th day 814 is increased to 105 units.With reference to figure 8v.The 15th day demand has satisfied.

Thereby system and method for the present invention goes for not expecting customer order, does not temporarily need during the artificial lifting elasticity above premeasuring.In this example, relatively stable 100 units every day that remain of aggregate demand in whole plan.Yet, if the customer order of receiving surpasses prediction, aggregate demand will begin to go up and elasticity during measure and also will go up.If this trend continues, system will send the signal of adjusting prediction to market department.
