Purpose: This paper investigates a batch scheduling problem where pre-processing is required for parts before processing, considering time-changing effects from part deterioration and operator learning-forgetting. Design/methodology/approach: A mathematical model was developed with the decision...

Purpose: Cloud manufacturing (CM) represents a new manufacturing paradigm that integrates distributed resources to provide on-demand services. The high consumer demand from various locations, coupled with the customizability and complexity of manufacturing, complicates task scheduling. In this...

The flexible job shop scheduling problem (FJSSP) is a complex optimization challenge that plays a crucial role in enhancing productivity and efficiency in modern manufacturing systems, aimed at optimizing the allocation of jobs to a variable set of machines. This paper introduces an algorithm to...

We consider a joint control of pricing and production in a two-item inventory system, where each item can be produced by its dedicated source or a shared flexible source, under the lost-sales setting. The demands of the two items are correlated. Due to the complexity caused by the lost-sales...

The Holt and Laury (2002) task is arguably the most widely employed method for eliciting individual risk attitudes in economics. However, although around 15% of standard experimental subjects fail to complete the task consistently, this fraction increases to an alarming 60-70% in the case of...

In this paper, we investigate under what market conditions regarding delivery lead time and due date reliability, the use of flexibility in daily working time in a job shop, can be beneficial. We use a working time decision rule that sets the working time for the next day equal to the value that...

Aspects of production and cost calculation are very important in a business activity that is oriented towards the sale of a product. Mekar Sari home industry does production separately in two places with a long distance, this is done for cost savings. The calculation of the cost of goods...

Due to their high initial investment costs, and excessive energy consumption, autoclaves are costly pieces of machinery to operate in manufacturing composite materials. They play a critical role in the process since they feed the subsequent processes. For more effective autoclave operations,...

This paper aims to model maintenance planning with a dynamic opportunistic approach for a job-shop production system. One issue in such a system is the positive or negative economic dependency. That is grouping maintenance activities may decrease or increase system costs. Furthermore, many...
