A scheduling system is proposed and developed for a special type of flow shop. In this flow shop there is one machine at each stage. A job may require multiple operations at each stage. The first operation of a job on stage j cannot start until the last operation of the job on stage j-1 has finished. Preemption of the operations of a job is not allowed. The flow shop that we consider has anothe...

SHOP (Simple Hierarchical Ordered Planner) is a domain-independent H T N planning system with the following characteristics. • SHOP plans for tasks in the same order that they will later be executed. This avoids some goalinteraction issues that arise in other HTN planners, so that the planning algorithm is relatively simple. • Since SHOP knows the complete world-state at each step of the planni...

In this article, we consider the minimization of the total tardiness in a flexible job-shop. In our knowledge, this criterion is not previously studied for this type of shop configuration. The total tardiness criterion was mainly considered in the single machine problem (Chu [Chu92] and Souissi et al. [SKC04]). Few references studied this criterion in a job-shop configuration. The priority rule...

T e incorporation of color Doppler systems on trans\'aginal probes has made it possible to evaluate the normally occurring cyclical haemodynamic changes in the I"male pelvis. In addition to the depiction of major \ascularchannels, small intraparenchymal vessels within the uterus and ovaries can be easily demonstrated. While color flo\\ imaging improves the ability to demonstrate \ascular struct...

The perceived affordances of an everyday object guide its user toward habitual movements and experiences. Physical actions that are not immediately associated with established body techniques often remain neglected. Can sound activate those potentials for action that remain latent in the physicality of an object? How can the exploration of underused and unusual bodily movements be fostered? Thi...

The "Gammaflow" automated assay concept of Brooker et al. (Science 194:270, 1976) has been adapted to the assay for urinary cyclic AMP in patients' samples on the now commercially available Squibb Gamma-FloTM system, a totally automated continuous-flow immunoassay instrument. The instrument aspirates the unknown sample, combines it with radioligand and specific antiserum, incubates the mixture,...

We present a comprehensive complexity analysis of classical shop scheduling problems subject to various combinations of constraints imposed on the processing times of operations, the maximum number of operations per job, the upper bound on schedule length, and the problem type (taking values “open shop”, “job shop”, “mixed shop”). It is shown that in the infinite class of such problems there ex...

A simulation based project is designed which can be practically implemented in a workspace (in this case, a barber shop). The design algorithm provides the user different time varying features such as number of people arrival, number of people being served, number of people waiting at the queue etc depending upon input criteria and system capability. The project is actually helpful for a modern...

Process scheduling is a classical problem in the field of production planning and control; in particular, effective job shop scheduling remains an essential component in today’s highly dynamic and agile production environment. This paper presents unified framework for solving generic job shop scheduling problems based on the formulation of a job shop into three main classes of problem, namely, ...
