More than a decade ago MSC offered the first parallel production system of MSC/NASTRAN. During this decade MSC has intensified its effort on parallel MSC/NASTRAN and is now ready to deliver MSC/NASTRAN V70.7, which contains very important new parallel features. This paper describes these exciting features and provides preliminary performance results for V70.7. We believe that this system marks ...

Clinical trials pose increasing challenges to sponsors and regulators in terms of execution complexity, timing constraints, risk management, and quality of scientific output. We show how the systematic use of clinical trial data standards, combined with the application of model driven semantic technology within the context of a metadata registry can provide a radical but more effective way to s...

This research focuses on the use of constrained capacity availability as a managerial decision variable in production systems. A simulation model was used to evaluate production system performance at various levels of constrained capacity before additional incremental levels of capacity were added. The results indicate that as levels of available capacity approach planned demand levels, or as d...

The paper studies the optimal production run length for a deteriorating production system. The optimal warranty cost is determined by a balance between the warranty cost of the manufacturer and the buyer during its warranty period. It is assumed that the elapsed time until the production process shift is age dependent and arbitrarily distributed. The objective is to minimize the total cost per ...

The purpose of this article is to develop a method for short and medium term capacity setting decisions for providing a market oriented level of available capacity for the investigated machine groups. An MTO (make to order) production system is considered. The basic concept is that the cumulative available capacity of the machine group has to be greater than or equal to the cumulative needed ca...

Many processes contribute to the speech production system. Brain damage can lead to a wide variety of disorders of the spontaneous production of sentences. Different symptoms of a sentence construction disorder, such as agrammatic and paragrammatic speech errors, are briefly described. An explicit model of the grammatical processes is proposed, and it is shown how the symptoms can be explained ...

Since the seminal eCash paper by Chaum, Fiat and Naor [4], there have been many improvements to the original protocol. However, a protocol constitutes only a single layer of a production system. We examine the feasibility of using some of these new eCash protocols in a more massive system that replaces our current physical cash system. Our examples are taken from the Australian economy, but sho...

Cellular production is maintained to be a popular manufacturing and management philosophy, which is increasingly interested and intensified. In this study, group technology cells design and implementation project in a real life glass mould production system is described. All the stages of the project, the difficulties encountered, the strategies developed that overcome these difficulties and th...

This paper considers the case of a one-stage production system with several products and operating under tight production capacity constraints. The production schedule is cyclical, and there are long and sequence dependent setup times. The production system is regarded to consist of two components, namely a production unit and an inventory unit. The performance, with respect to inventory costs,...

Consideration of quality implicitly introduces the need to adjust inputs in order to obtain desired output. Output evaluation must consider quality as well as cost. Real decisions may involve other objectives as well. Production problems often involve a dynamic situation where the relationship between cost and quality must be experimentally developed. The proposed method is to use regression as...
