Work flows in a job-shop are determined not only by the release load and the time between release factors, but also by the number of accepted orders. There has been extensive research on workload and input-output control aiming at improving the performance of manufacturing operations in...

We consider the problem of planning future order releases in hierarchical production planning and control systems. An established research direction is the clearing function concept: The planned material flow through a production unit is modeled by inventory balance equations for WIP and final...

The paper presents a simulation study that compares multi-period models for order release optimisation (Input/Output Control with fixed lead times and a clearing function model) with a traditional workload control-based order release mechanism (control of aggregate workload with periodic...

Card-based systems can be simple yet effective means of controlling production. But existing solutions, such as Kanban, do not typically apply to the job shops often found in make-to-order companies. In response, a card-based approach to Workload Control known as COBACABANA – COntrol of...

Subcontracting can be an important means of overcoming capacity shortages and of workload balancing, especially in make-to-order companies characterized by high variety, high demand variation and a job shop configuration. But there is a lack of simple, yet powerful subcontracting rules suitable...

A relevant segment of job shop environments has to cope with specific routing complexity. When order routings are long or assembly structures exist, performance problems arise in the application of traditional job shop control concepts based on workload control (WLC). This paper investigates how...

The IT revolution generated important changes on society and firms. Under these circumstances, the companies’ management reaches to the five-generation assuring, base on plurality, fast decisions making, and an equal treatment of the employers taking into consideration the high level of their...

The objective of this paper is to estimate technical efficiency in retailing; and the influence of inventory investment, wage levels, and firm age on this efficiency. We use the output supermarket chains¿ sales volume, calculated isolating the retailer price effect on its sales revenue. This...

This article reviews The Power of Productivity by William W. Lewis and Transforming the European Economy by Martin Neil Baily and Jacob Funk Kirkegaard. While Lewis postulates a single silver bullet for productivity growth, namely the freedom of consumers, Baily and Kirkegaard advocate a broader...

The use of screening contracts is a common approach to solve supply chain coordination problems under asymmetric information. One major assumption in this context is that subjects will rather use their private information strategically than to reveal them truthfully, if they do not get any...
