Dispatching rules are usually applied to schedule jobs in Flexible Manufacturing Systems (FMSs) dynamically. Despite their frequent use, one of the drawbacks that they display is that the state the manufacturing system is in dictates the level of performance of the rule. As no rule is better than all the other rules for all system states, it would highly desirable to know which rule is the most...

Many Emergency Medical Service (EMS) systems worldwide handle emergency rescues as well as patient transports and dispatchers need to assign ambulances to incidents manually throughout the day. The management of the complex system together with the manual assignments can easily create stress for and pressure on the dispatchers. Mathematical algorithms can help improving the dispatching quality,...

In this paper we address the real-time capabilities of P-NET, which is a multi-master fieldbus standard based on a virtual token passing scheme. We show how P-NET’s medium access control (MAC) protocol is able to guarantee a bounded access time to message requests. We then propose a model for implementing fixed prioritybased dispatching mechanisms at each master’s application level. In this way...

We develop a simple model that links the adoption of a productivity-enhancing technology to increased vertical integration and a less skilled workforce. We test the model’s key prediction using novel microdata on vehicle ownership patterns from the Economic Census during a period when computerized dispatching systems were first adopted by taxicab firms. Controlling for time-invariant firm-speci...

Value prediction can be used to break data dependency between instructions, ensuring simultaneous handling of multiple instructions in processors. When such instruction-level parallelism is lifted, it helps reduce a processor’s idle time and thus enhances the performance. To improve the accuracy of value prediction at low additional cost, this paper presents a new dispatching mechanism with spe...

-There has been a lot of research about scheduling manufacturing systems with dispatching rules in the past. However, most studies concentrate on simplified scenarios considering only one type of resource, usually machines. In this study dispatching rules are applied to a more realistic scenario, which is dual constrained by machines and operators and has a re-entrant process flow. Interdepende...

Data warehousing hastens the process of retrieving information needed for decision making. The spider web diversity between both end-users and data marts increases traffic, load, and delay in accessing the requested information. In this research, we have developed a query dispatching tool facilitating the access to the information within data marts, eventually data warehouse in fast, and an org...

The remarkable growth of crowdfunding has sparked academic interest. By collecting small contributions from a large number of individuals, entrepreneurs, artists and other individuals and organizations can raise considerable amounts of money. Despite the increasing academic interest in this topic, there still appears to be a lack of understanding regarding the factors that determine individuals...
