Earlier research has found that the presence of setup time variance can cause an adverse effect on waiting time and inventory as one reduces setup time for a product on a single machine that processes a number of products in a cyclic production system [Sarkar, D., Zangwill, W.I., 1991. Variance effects in cyclic production systems. Management Science 37 (4) 444–453; Zangwill, W.I., 1987. From E...

In this paper we propose a method, based on a Set Membership approach, for the estimation of nonlinear regressions models. At the contrary of most of the existing identi...cation approaches, the method presented in this paper does not need any assumption about the functional form of the model to be identi...ed, but uses only some prior information on its regularity and on the size of noise corr...

The neutrino long wavelength (just-so) oscillation is reconsidered as a solution to the solar neutrino problem. In the light of the presently updated results of the four solar neutrino experiments, the data fit in the just-so scenario substantially improves and becomes almost as good as in the MSW scenario. Surprising result of our analysis is that best fit is achieved when the oscillation occu...

Modern day industry is becoming leaner by the day. This demands engineers with an in-depth understanding of lean philosophies. Current methods for teaching lean include hands-on projects and simulation. However, simulation games available in the market lack simplicity, ability to store the results, and modeling power. The goal of this research is to develop a virtual simulation platform which w...

Postcompletion error (Byrne & Bovair, 1997) is a robust form of routine procedural error that can be difficult to prevent. However, Chung and Byrne (2004, 2008) reported the complete elimination of this error with a highly aggressive cue, one which was just-in-time, highly specific, and highly visually salient. This paper reports three experiments designed to investigate the role of each one of...

Time-based supply chain management is already realized to a certain extent – especially on a regional or national level. But in an international context the time focus is only visible in particular supply chain segments as for example the just-in-time delivery. Other areas of the global supply chain are only allowing a continuous parts flow with the help of stocks. For reducing these stock leve...

Just‐In‐Time (JIT) production has received a great deal of attention, worldwide, since its introduction in Japan a few decades ago. It has been well documented that some of the main benefits of JIT implementation are reduction of inventories, lead‐time reduction, and cost savings. Most of the previous research on the impact of JIT on firm performance has either been anecdotal (one‐firm studies)...

Cognitive scientists have shown increased interest in diagrams in recent years, but most of the focus has been on spatial representation, not conventions for representing time. We explore a variety of ways in which time is represented in diagrams by one research community: scientists investigating circadian rhythms at the behavioral and molecular levels. Diagrams that relate other variables to ...
