Optimal Aggregate Production Planning with Fuzzy Data

ثبت نشده
چکیده

This paper investigates the optimization problem of multi-product aggregate production planning (APP) with fuzzy data. From a comprehensive viewpoint of conserving the fuzziness of input information, this paper proposes a method that can completely describe the membership function of the performance measure. The idea is based on the well-known Zadeh’s extension principle which plays an important role in fuzzy theory. In the proposed solution procedure, a pair of mathematical programs parameterized by possibility level α is formulated to calculate the bounds of the optimal performance measure at α . Then the membership function of the optimal performance measure is constructed by enumerating different values of α . Solutions obtained from the proposed method contain more information, and can offer more chance to achieve the feasible disaggregate plan. This is helpful to the decision-maker in practical applications. Keywords—fuzzy data, aggregate production planning, membership function, parametric programming

Solving a generalized aggregate production planning problem by genetic algorithms

This paper presents a genetic algorithm (GA) for solving a generalized model of single-item resource-constrained aggregate production planning (APP) with linear cost functions. APP belongs to a class of pro-duction planning problems in which there is a single production variable representing the total production of all products. We linearize a linear mixed-integer model of APP subject to hiring...

Fuzzy-genetic approach to aggregate production-distribution planning in supply chain management

Aggregate production–distribution planning is one of the most important activities in supply chain management(SCM). When solving the problem of APDP, we are usually faced with uncertain market demands and capacities in production environment, imprecise process times, and other factors introducing inherent uncertainty to the solution. Using deterministic and stochastic models in such conditions ...
