The impact of OPT and TPM on the economic production quantity

International Journal of Systems Science, 1995
In manufacturing systems, the material flow is influenced by a number of factors, such as batching policies, capacity of machines, machine breakdowns, etc. Realizing the role of batching policies and reliability of machines in production systems, a mathematical model is presented here for determining optimal batching policies with the objective of ...

Economic production quantity for profit maximization

International Journal of Systems Science, 1990
In certain circumstances a relationship between unit contribution and producing output may exist in the classical economic production quantity (EPQ) production. We discuss an EPQ model with unit contribution dependent on production output and formulate the problem as signomial geometric problem (SPG) We show that a closed form optimal solution is ...

Economic production order quantity and quality

International Journal of Production Research, 2011
The purpose of this study is to integrate a conventional production-inventory management approach and a process-quality design approach so as to promote quality and reduce costs. Because the integration of these two approaches into a single system is conducted under the influence of a deterioration process, estimated costs of production must be ...

Outsourcing Rework of Imperfect Items in the Economic Production Quantity (EPQ) Inventory Model With Backordered Demand

IEEE Transactions on Systems, Man, and Cybernetics: Systems, 2019
This paper deals with an economic production quantity (EPQ) model with imperfect items and backordered demand. The manufacturing system is imperfect and generates a fraction of imperfect items, which is a random variable with a distribution function ...

Economic production quantity for a manufacturing system with a controllable production rate

Production Planning & Control, 1997
Abstract Jamal and Sarker developed a model for determining the economic production quantity for fixed-interval demands. Some researchers have suggested that controlling production rate might be a solution to some quality and inventory problems. In this paper, we extend Jamal and Sarker's model by considering the production rate to be controllable.

Determination of economic production quantity in a multi-stage production system

Production Planning & Control, 1994
Abstract In this paper two models have been suggested for determining economic production quantity in a multi-stage production system. The demand for the product is assumed constant and it is supplied by manufacturing the product in equal production runs. The production lot is transported in a number of sub-batches of equal sizes.

Optimal inspection and economical production quantity strategy for an imperfect production process

International Journal of Systems Science, 2006
This paper considers a problem relating to the integration of production, maintenance, inspection and inventory. The optimal inspection interval, inspection frequency and production quantity were studied, assuming an imperfect production process and a maintenance policy that permits minimal repair, shortages and inspection errors.

An Economic Production Quantity Problem with Fuzzy Backorder and Fuzzy Demand

2013
Optimization models based on fuzzy set theory are relevant to the process industry, where there are many uncertainties that are inherently fuzzy. In this paper, we incorporate backorders (i.e the inventory to go below zero) and cycle time in a fuzzy Economic Production Quantity (EPQ) model.

An economic production quantity model with backlogging and imperfect rework process for uncertain demand

International Journal of Production Research, 2019
This paper deals with a lot-sizing problem in the economic production quantity model with imperfect production processes and failure in repair where a Brownian motion process governs the inventory level variation. We assume that the unsatisfied demand is

Economic Production Quantity for Supply Chain System with Volume Flexibility

2005 IEEE International Conference on e-Technology, e-Commerce and e-Service, 2005
A production-delivery system with volume flexibility in a single-stage supply chain is considered in this research. In this system, raw materials and/or component parts are procured from suppliers and processed into finished products, which are delivered to customers periodically at a fixed quantity with a fixed interval of time.
