Aggregate versus disaggregate production planning: a simulated experiment using LDR and MRP

Abstract

Within the past several years, considerable research has been devoted to the aggregate production planning problem starting with the pioneering work of Holt et al. (1955)and the resulting Linear Decision Rule (LDR). However, researchers have also recognized that developing optimal aggregate production plans, per se, is not sufficient for solving real problems; these plans have to be disaggregated into specific schedules for specific products. Consequently, the thrust of current research is on the 'disaggregation' problem. Simultaneously a number of companies have been installing MRP systems with reports of significant improvements in inventory control, production planning, work force scheduling and production costs. This paper reports on an experiment which was designed and conducted to compare the effectiveness of the 'aggregate-disaggregate' and MRP approaches to production planning in a simulation environment. LDR was used as the optimal aggregate technique in the aggregate-disaggregate approach. The results appeared to favour the MRP approach.

New Developments and Decision-makings in Production and Retailing

“…Production planning decision-making involves a wide variety of research issues, including master production schedule (Venkataraman and Nathan 1994;Sahin et al 2008), material requirements planning (Le et al 2004;Dolgui and Prodhon 2007), manufacturing resource planning (MRP II) (Sawyer 1990;Wazed et al 2010;Drexl and Kimms 2013), enterprise resource planning (Ehie and Madsen 2005;Parush et al 2007), aggregate planning (Lee et al 1983;Jamalnia and Soukhakian 2009;Bushuev 2014), and so on. A great number of papers have been published in this area and some researchers provided comprehensive reviews (Dolgui andProdhon 2007, Wang et al 2009;Mula et al 2010;Wazed et al 2010).…”

Optimización de Órdenes de Producción Utilizando Algoritmo Genético

“…La toma de decisiones en la planeación de la producción involucra una amplia variedad de temas, incluyendo el programa maestro de producción, [2] , [3], planeación de requerimientos de materiales (MRP), [4] , [5], software de gestión integrada (ERP), [6], [7] y la planeación agregada, [8], [9]. En la actualidad existen investigaciones de planeación y programación de la producción considerando diferentes factores y restricciones donde destacan: Los autores [10], abordaron el problema de planeación y programación de la producción en un entorno de producción multiproducto y multi-proceso considerando el tamaño de lote.…”
