Abstract

In a real life application, we model the production planning and control function in a textile plant as a problem in planning and scheduling in a flexible flowshop. For practical considerations the total problem is divided into two parts: a ‘capacity loading function’ and a ‘scheduling function’, both undertaken over a finite planning horizon of six weeks. The ‘loading’ was optimized via linear programming. The ‘scheduling’ was effected via a number of heuristics that accommodated a variety of (oftentimes contradictory) objectives. The input to the combined control scheme was implemented on a spreadsheet. Several reports resulted containing information of interest to shop floor personnel as well as to management. A side benefit to the production planning system was a marketing model that helped the design of the firm’s marketing strategy.
