Forward planning for aggregate production
2019This project was commissioned with the aim of modernising the production planning systems at CRMC through the introduction of a numerical based tool capable of planning production ahead of time. Project Aim This project consisted of three major goals: 1. Develop an understanding of quarry production systems 2.

Aggregation and disaggregation in hierarchical production planning
European Journal of Operational Research, 1984Abstract This paper reports on a simulation study of hierarchical planning procedures, which can support a material requirements planning system. Data for this study have been obtained from a Swedish manufacturing company. The three final products considered in the simulations represent a major part of this company.

A New Approach to Aggregate Production Planning
IIE Transactions, 1986Abstract This paper proposes a new framework for modelling aggregate production planning problems in which emphasis is placed upon offering the user the flexibility to specify (1) the production options to be employed, (2) the relationships among those options (some of which may be highly situation-specific), and (3) the relevant cost structure.

Convex optimisation for aggregate production planning
International Journal of Production Research, 2013This paper presents a new solution approach to the problem of aggregate production planning (APP). As identified by many researchers, the APP cost function is convex and piecewise. Thus, the convex optimisation approach can be applied to the APP problem.

Production Planning At Different Levels Of Aggregation
1998This chapter extends the flow control approach to the problems with multiple facilities and either single or multiple products characterized by simple structures. It, thus, deals with an intermediate hierarchical level that bridges aggregate production planning and detailed production scheduling characterized by complex product structures. Specifically,

Aggregate Planning with Learning Curve Productivity
Management Science, 1976Research reports of others indicate that many manufacturing organizations experience (a) the probiem of aggregate planning, and (b) experience systematic productivity changes throughout the “life” of a product. Methods for resolving (a) and for quantifying (b) have been developed and applied independently in the operations management literature.

Aggregate Model for Refinery Production Planning
2012Abstract With increasing crude oil price, refining of crude oil blends becomes common practice. This paper is aimed at developing a mathematic model for CDU and VDU in GAMS through information obtained from corresponding rigorous modelling in Aspen HYSYS. This model for CDU and VDU will be combined with empirical models for fluid catalytic cracker (

Five Approaches to Aggregate Production Planning
A I I E Transactions, 1975Abstract Production scheduling problems are reviewed briefly and the smoothing problem is defined as planning the aggregate production level for each period in a given horizon to meet forecast demand. Five approaches to the problem are reviewed: (1) the HMMS linear decision rule for production and employment; (2) the DE rule for production, in which ...
