This study investigated the effect of total quality management factors on firm's operational performance in Korea. We used a regression linear analysis to conduct this research study. The samples used to conduct this analysis were selected form World Bank's Business Environment and Enterprise...

We demonstrate the need to view in a dynamic context any decision based on limited information. We focus on the use of product costs in selecting the product portfolio. We show how ex post data regarding the actual costs from implementing the decision leads to updating of product cost estimates...

5S can be viewed as a system of workplace rules devised to create a safe and productive work environment and to provide efficient and effective realization of business tasks. Its implementation is expected to reduce defects, improve quality, increase safety and the morale of the employees, and...

Long-term relationships are generally believed to incentivize investments better than short-term relationships. We show that while this is true for quality investments, it is not always true for responsibility investments. In particular, when a reliable and an unreliable supplier compete for the...

In a recent paper, Egghe [Egghe, L. (in press). Mathematical derivation of the impact factor distribution. Journal of Informetrics] provides a mathematical analysis of the rank-order distribution of journal impact factors. We point out that Egghe's analysis relies on an unrealistic assumption,...

In this paper, we consider a make-to-stock production system with known exogenous replenishments and multiple customer classes. The objective is to maximize profit over the planning horizon by deciding whether to accept or reject a given order, in anticipation of more profitable future orders....

China is the world's largest user of industrial robots. In 2016, sales of industrial robots in China reached 87,000 units, accounting for around 30 percent of the global market. To put this number in perspective, robot sales in all of Europe and the Americas in 2016 reached 97,300 units...

Trade credit is a widely adopted industry practice. Prior research has focused on how trade credit benefits firms by improving vertical supply chain relationships. This paper offers a novel perspective by examining whether trade credit benefits suppliers through a horizontal channel. Under the...

We investigate the situation where a customer experiencing an inventory stockout at a retailer potentially leaves the firm's market. In classical inventory theory, a unit stockout penalty cost has been used as a surrogate to mimic the economic effect of such a departure; in this study, we...

This paper demonstrates optimal policies for capacitated serial multiechelon production/inventory systems. Extending the Clark and Scarf (1960) model to include installations with production capacity limits, we demonstrate that a modified echelon base-stock policy is optimal in a two-stage...
