I+1(in step 3) or other handler.As above-mentioned, the design of turnover table will be a key point of above-mentioned execution efficient.
Fig. 5 is the flow process according to turnover table method for building up of the present invention.As shown in Figure 5, the foundation of above-mentioned turnover table comprises three steps: the board number (a step equipmentnumber) of each processing procedure of each product of the amount of commenting in the overhours in each production tunnel (astep process time) and each processing procedure in each production tunnel (S1); According to this each processing procedure of each product in overhours in each production tunnel and the board number of this each processing procedure in each production tunnel calculate in each stage each processing procedure in the working ability (a step work ability) in each production tunnel (S2); And gather each processing procedure in (summary) each stage in the working ability (step work ability) in each production tunnel to produce a turnover table (from-to table) (S3).
For above-mentioned overhours of the amount of commenting and board number, indicator gauge 1 in Fig. 6 a and Fig. 6 b.In table 1, a product P

2,4This stage.Board in each stage corresponds to an overhours (process time) and a production tunnel (channel).For example, in this example, stage S
1,1In board E
1Correspond to P overhours
1,1,1And production tunnel T
1, and stage S
1,3In board E
1Correspond to P overhours
1,1,2And production tunnel T

1One second overhours.Similarly, overhours P
2,4,1Represent board E
4Be used for product P
2One first overhours, the rest may be inferred, other is also identical.Same board group's board has similar overhours, and we get its aviation value and are defined as each processing procedure the overhours in each production tunnel (step process time).For example, at production tunnel T
1In, each processing procedure is in the AP overhours in each production tunnel
1,1,1Equal P overhours
1,1,2And P
1,2,1Aviation value.Again, at production tunnel T
2In, each processing procedure is in the AP overhours in each production tunnel
1,1,2Equal P overhours
1,3,1Aviation value.The rest may be inferred, and other each processing procedure calculating the overhours in each production tunnel also duplicates.In addition, board can be used in the different phase of identical product.For example, be used for product P
1, board E
1Be used in processing procedure (operation) O
1,1, O
1,3, O
1,4In, and board E
2Be used in processing procedure (operation) O
1,1, O
1,4In.Therefore, for product P
1Each processing procedure, board E
1Occupation coefficient (utilityprobability) be 1/3 and board E
2Occupation coefficient be 1/2.Because same board may cross over the different stages, so we define a certain board real quantity (equipmentId number) that is assigned to different phase and the stage quantity of crossing over and are reciprocal relation.For example, if PM
1It is product P
1To the ratio of each product summation amount, then board E
1At stage S
1,1In real quantity be PM
1Multiply by 1/3, and board E
2At stage S
1,1In real quantity be PM
1Multiply by 1/2.Similarly, PM
2It is product P
2To the ratio of each product summation amount, and PM in this example
1+ PM
2=1.Yet, can surpass two kinds of products on the practice, but the ratio summation of all products is 1.Each processing procedure is in the board number (step equipmentnumber) in each production tunnel, for example N
1,1,1Be by PM
1Multiply by (1/3+1/2) and get.The rest may be inferred, and other each processing procedure can calculate in the same manner and get in the board number (step equipment number) in each production tunnel.Each processing procedure that calculates and get is listed in the form shown in Fig. 6 a and Fig. 6 b in the board number (step equipment number) in each production tunnel in overhours and each processing procedure in each production tunnel.Utilize above table, overhours and each processing procedure of each processing procedure in each production tunnel that calculates each production tunnel is the working ability (step work ability) (S2 of Fig. 5) of each processing procedure of a certain product in each production tunnel in the ratio of the board number (step equipment number) in each production tunnel, and the working ability (step work ability) of each processing procedure in each production tunnel in each stage is summarized in (S3 of Fig. 5) in the form.
Therefore, as shown in Figure 7 a turnover table (from-to table) is established.In Fig. 7, its value is littler better when working ability (work ability), represents turnover rate (turn rate) faster.High turnover rate means lacking of semifinished piece accumulation.With reference to above-mentioned turnover table, when being stored in a storage when the goods operation of finishing a collection of expectation and with it, above-mentioned turnover table can be inquired about according to the stage and the board group of next processing procedure by system, this batch goods are sent to the storage of appointment.One production tunnel can correspond to the storage (stocker Id) of most convenient storage/access.Because the board of identical or similar functions can be placed in different production tunnels or or even different floor in, so stage and machine get on well with others group might directed a plurality of storages.As seen in Fig., (S*

Again, each storage is provided with a full-water level and indicates (HWM), in corresponding storage, to reserve a buffer zone (buffer region), that can keep in the goods that will deliver to next processing procedure treats the car working area, or indicates and a collection ofly be about to that processed goods are temporary to indicate (LWM) up to a low water to another storage and send signal with till removing this full-water level and indicating (HWM).When low water indicates (LWM) when sending signal and indicating (HWM) to remove this full-water level, this batch be about to processed goods from above-mentioned another storage return to former storage with as usual as process.
Generally speaking, the invention provides a storage and a management process that is used for a warehousing system with multiple floors, it is in conjunction with the way to manage that pushes away and draw function and form guiding to send, come optimization to distribute semifinished piece (work-in-process in the factory, WIP) storage of each in above-mentioned many floors system is so as to using each storage efficiently.We use instant production information and computer arithmetic capability apace effectively, the wisdom optimal path and the best haulage time algorithm of a more complete consideration production and manufacturing environment of development, avoid each workstation to cause production capacity waste and reduce automatic guided vehicle transporting round carrying between standby storage to, and then shorten the deadline of whole batch because of congested or scarce material phenomenon.
