Specific implementation mode
It is with reference to the accompanying drawings and embodiments, right in order to make the object, technical solution and advantage of the application be more clearly understood The application is further elaborated.It should be appreciated that specific embodiment described herein is only used to explain the application, not For limiting the application.
Production scheduling method provided by the present application, can be applied in the production environment of make-to-order production, i.e. manufacturing enterprise Receive the order of client, production scheduling is then carried out according to the actual state of each production common property, by the Order splitting of receiving to each Production plant is produced, this is because different factory cost valence, address, production capacity, producing line have differences, therefore, from For entreprise cost and the angle of lean production, it is more desirable under the premise of the cooperation between maintaining each factory so that enterprise Production cost and customer satisfaction highest.Assuming that manufacturing enterprise carries out production scheduling as unit of day, it will be under the order of yesterday Plan to each factory;And every producing line of factory all checks pass through before manufacture, does not break down in process of production.
In one embodiment, as shown in Fig. 2, providing a kind of production scheduling method, including step:
S200 obtains customer order information.
Customer order information can specifically include:The life of Customer ID, customer address, product type, product needed for client Produce the date etc. of batch number quantity, the neat set date of product, the beginning production schedule.Manufacturing enterprise receives client to the pre- of product It is fixed, generate corresponding customer order information.
S400 parses customer order information by default tabu search algorithm, obtains customer order information and corresponds to Multiple global solutions, the number of the target component of global solution is at least 2.
Tabu search algorithm, tabu search algorithm are a kind of meta-heuristic random search algorithms, it is initial feasible from one Solution is set out, and selects a series of specific direction of search as souning out, and selection, which is realized, allows specific target function value to change at most It is mobile.And traditional tabu search algorithm is to make it so needing modified Tabu search algorithm for the algorithm of single object optimization It can realize multiple-objection optimization.Default tabu search algorithm target component in the application is at least 2, but due to being provided with multiple mesh Mark parameter so that the quantity for the solution that default tabu search algorithm obtains is not limited to one.Target component refers to default taboo The target component of searching algorithm optimization, in one embodiment, target component can specifically include capacity loss, required be produced into This and client are with a distance from factory.
The order information of client is parsed by preset tabu search algorithm, obtain meet optimization aim with visitor The corresponding global solution of family order.In one embodiment, parsing global solution can meet owning for the sum of target component minimum Solution.
S600 searches the global solution of difference minimum between target component in global solution, and most by difference between target component Small global solution is as optimal solution.
During multiple-objection optimization, so that each target is minimum simultaneously, this is simultaneously unrealistic, in fact, being pursued Multi-objective optimization question, be to enable multiple targets being optimal " as far as possible " simultaneously, and " " be optimal as far as possible Scheme also can there are many kinds of, so a variety of " as far as possible " in optimal scheme, it is required obtain target function value minimum That solution.The value of integration objective object function is 10 in one of the embodiments, and (a1, a2, a3) indicates production capacity respectively Loss, cost, distance, then one group of possible global solution is (10,0,0) or (Isosorbide-5-Nitrae, 5) or (8,1,1) or (3,4,3), this four The general objective functional value of group global solution all meets minimum value, but single solution is not the optimal solution in single goal, such as (10,0,0) The cost and distance of this group solution are 0, it is clear that can not possibly be existed in practical business, for another example the cost of (8,1,1) and apart from right and wrong Often small value, and production capacity loss is larger, it is clear that there is solution combination better than this.(3,4,3) are targets in this 4 global solutions The solution of the direct difference minimum of parameter, it is possible to as the global solution of this arrangement scheme.

After obtaining global solution, even if then target can be joined with the absolute value of difference between parameters in global solution The global solution of the sum of absolute value of difference minimum is as optimal solution between number.Absolute difference is most between parameters in global solution Small is the global solution of difference minimum between target component.Solving the process of optimal solution in one of the embodiments, can lead to Overbalance device is realized, it is assumed that there are three the targets of tabu search algorithm, and the course of work of balancer specifically comprises the following steps:
1) three targets indicate d12 by obj1, obj2, obj3 respectively, and d13, d23 indicate the difference between three targets respectively Absolute value;
2) any one in d12 or d13 or d23 is calculated, is deposited this value as a key-value pair in a list, The length L of this list is configured by the parameter of preset tabu search algorithm, specifically can be according to preset TABU search Multiple target distance parameter in algorithm is configured;
3) towards the slightly smaller value of the direction removal search of max (obj1, obj2, obj3), one group of new desired value is obtained, is returned to Step 1), when calculating to the L+1 or when the value that step 2) is calculated 3 times (3 are target number) does not occur Change, then return to the key of list intermediate value minimum, a solution as this wheel TABU search iteration returns to argument scalar functions. When calculating the key-value pair in L every time in one of the embodiments, it can look for looking for according to the direction of a upper key-value pair , it can comparatively fast find minimum value.
