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 ...

Experience-based continuous learning is essential for improving products, processes, and technologies in emerging as well as established areas of business and engineering science. It can be facilitated by casebased organizational learning, meaning that relevant experience is captured in the form of cases for reuse in a corporate experience repository. For obvious reasons, learning from experien...

Interpreted languages are widely used due to ease to use, portability, and safety. On the other hand, interpretation imposes a significance overhead. Just-inTime (JIT) compilation is a popular approach to improving the runtime performance of languages such as Java. We compare the performance of a JIT compiler with a traditional compiler and with an emulator. We show that the compilation overhea...

in this paper, a multi-product single machine scheduling problem with the possibility of producing defected jobs, is considered. we concern rework in the scheduling environment and propose a mixed-integer programming (mip) model for the problem.  based on the philosophy of just-in-time production, minimization of the sum of earliness and tardiness costs is taken into account as the objective fu...

This paper considers Just-In-Time Job-Shop Scheduling, in which each activity has an earliness and a tardiness cost with respect to a due date. It proposes a constraint programming approach, which includes a novel filtering algorithm and dedicated heuristics. The filtering algorithm uses a machine relaxation to produce a lower bound that can be obtained by solving a Just-In-Time Pert problem. I...

this paper investigates the problem of just-in-time permutation flow shop scheduling with limited buffers and linear job deterioration in an uncertain environment. the fuzzy set theory is applied to describe this situation. a novel mixed-integer nonlinear program is presented to minimize the weighted sum of fuzzy earliness and tardiness penalties. due to the computational complexities, the prop...
