Aggregate Production Planning

SSRN Electronic Journal, 2011
This report reviews the particulars provided in a case study that requires engineering analysis in reviewing the operations of a furniture manufacturer's processes in determining how best to meet the demand projections while holding the expenditures for this organization.

Forward planning for aggregate production

2019
This 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.

Accounting for productivity losses in aggregate planning

International Journal of Production Research, 2001
The aggregate planning literature fails to account correctly for productivity losses incurred by employee layoffs and hires. Moreover, the literature is mostly silent on the productivity losses associated with other capacity changes such as multiple shifts and overtime.

Aggregation and disaggregation in hierarchical production planning

European Journal of Operational Research, 1984
Abstract 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, 1986
Abstract 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.

Aggregate Model for Refinery Production Planning

2012
Abstract 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 (

Production Planning At Different Levels Of Aggregation

1998
This 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,

Convex optimisation for aggregate production planning

International Journal of Production Research, 2013
This 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.

Aggregate Planning with Learning Curve Productivity

Management Science, 1976
Research 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.
