Chang, D Y-M (1986) RESQUE: A resource based simulation system for construction process planning. PhD thesis, University of Michigan, USA.
Abstract
RESQUE, a RESource based QUEueing network simulation system, was developed to model complex resource flows typical for construction processes. A RESQUE model consists of a process chart and a process detailing segment. A process chart is a network of four basic modeling elements which show operations and resource flows in the process. The chart is an excellent vehicle of communications, because it can be easily drawn and understood by construction people as well as planners. The process detailing segment is an overlay to the process chart. That is, the functional details of operations and resource flows (as shown in the process chart) are specified in this segment by using a set of PDL (Process Description Language) statements. The PDL statements provide a means of defining these process characteristics: (1) Resource Characterization. Each resource unit can have its own property which may affect operation behaviors. (2) Resource Calling. Operation resource requirements are defined. They can depend on specific resource properties. (3) Resource Holding. Operation cycle times are specified. They can be defined as random variables which depend on specific resource properties. (4) Resource Handling. Operations handle resources. Handling patterns, such as assembling and disassembling, are defined. (5) Resource Routing. Resources, after they have been handled at operations, can be routed according to different criteria. The criteria, such as properties and other conditions in the process model, are specified. As a result, the resource (property) dependent nature of a construction process can be realistically defined. The process detailing segment also provides a feasible interface to the computerized RESQUE simulator which predicts process performance according to the input. Different process alternatives can be defined and simulated by modifying the PDL statements in the process detailing segment while maintaining the simplicity of the process chart. In addition to construction processes, RESQUE can model any processes which are sensitive to resource availabilities and resource properties. The RESQUE system also provides a framework for future extensions which will lead to new dimensions in network based simulations.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
