Aggregate production planning with workforce transferring plan for multiple product types
Production Planning and Control, 2003This paper presents the aggregate production planning for multiple product types where the worker resource can be transferred among the production lines. A mathematical model was formulated in spreadsheet format. Then the spreadsheet-solver technique was used as a tool to solve the model.

Uncertain aggregate production planning
Soft Computing, 2012Based on uncertainty theory, multiproduct aggregate production planning model is presented, where the market demand, production cost, subcontracting cost, etc., are all characterized as uncertain variables. The objective is to maximize the belief degree of obtaining the profit more than the predetermined profit over the whole planning horizon.

Aggregation of Product Data for Hierarchical Production Planning
Operations Research, 1981When applying an aggregate view to production planning, the production system is given a hierarchical structure. The problem description at the upper level (which is less detailed) concerns product groups and machine groups rather than individual products and machines. This means that product structures and capacity requirements also must be expressed

Aggregate planning for production
Business Horizons, 1967Abstract At its inception modern aggregate planning does pose difficulties, but these can be overcome—with results that greatly benefit the manager. For example, in developing this kind of planning one might have to consider whether inventory or size of the work force would absorb demand fluctuations.

Production Switching Heuristics for the Aggregate Planning Problem
Management Science, 1978A number of approaches to the aggregate planning problem have been proposed in the literature, yet experience suggests that industrial concerns seldom use these models in actual planning situations. This paper describes a modified random walk production-inventory heuristic for the problem which should appeal to managers on the basis of simplicity as ...

An uncertain aggregate production planning model for vegetables
2017 13th International Conference on Natural Computation, Fuzzy Systems and Knowledge Discovery (ICNC-FSKD), 2017Aggregate production planning is made for the future production and there might be many unpredictable disruptions in actual production, which makes the historical data become unreliable. Meantime, long lead-times, short sales cycle, fast updating speed and volatile markets of the perishable vegetables usually makes the demand, deterioration rate and ...

Aggregate planning in crew-loaded production environments
Computers & Operations Research, 1989Abstract Virtually all existing optimization techniques for the aggregate planning problem incorporate continuous decision variables. However, predetermined shift settings in crew-loaded production operations often require the decision variables to be discrete values.

Optimal Disaggregation of Aggregate Production Plans
Management Science, 1971Aggregate Production Planning (APP) is concerned with a minimum cost adaptation of some production process to demand fluctuations, by means of controlling overall production rate (P) and workforce size (W). Disaggregation aims at allocating P and W to individual products such that an optimal sales program is obtained.

Fuzzy modelling and simulation for aggregate production planning
International Journal of Systems Science, 2003The market demands and financial constraints in medium- to long-term production planning are often subject to uncertainties. As an extension of the author's previous paper, this paper focuses on a formulation and simulation analysis for multi-product aggregate production-planning problems with fuzzy demands and fuzzy capacities.
