Job Shop Scheduling Problem: An Overview, Amr Arisha, Paul Young, Mohie El Baradie
Job Shop Scheduling Problem: An Overview, Amr Arisha, Paul Young, Mohie El Baradie
Conference papers
The Job-shop scheduling is one of the most important industrial activities, especially in manufacturing planning. The problem complexity has increased along with the increase in the complexity of operations and product-mix. To solve this problem, numerous approaches have been developed incorporating discrete event simulation methodology. The scope and the purpose of this paper is to present a survey which covers most of the solving techniques of Job Shop Scheduling (JSS) problem. A classification of these techniques has been proposed: Traditional Techniques and Advanced Techniques. The traditional techniques to solve JSS could not fully satisfy the global competition and rapidly changing …
The Effects Of Budgetary Constraints, Multiple Strategy Selection, And Rationality On Equilibrium Attainment In An Information Warfare Simulation, Steven W. Tait
Theses and Dissertations
Information warfare (IW) has developed into a significant threat to the national security of the United States. Our critical infrastructures, linked together by information systems, are increasingly vulnerable to information attack. This study seeks to understand some of those factors which affect the ability of an individual to make accurate decisions in an IW environment. The study used game theory to analyze the behavior of decision-makers within an IW simulation. The IW game model is based on a set of games known as infinitely repeated games of incomplete information. It uses the Bayesian Nash equilibrium concept to determine the strategy …
An Analysis Of The Acquisition Process For Simplified Acquisition Of Base Engineering Requirements (Saber) Contracts And Its Potential Impact On Contractor Performance, Brian J. Heaps
Theses and Dissertations
The Simplified Acquisition of Base Engineering Requirements (SABER) contract's main purpose is to expedite contract award of civil engineer requirements through the issuance of individual delivery orders. The contract contains a collection of detailed task specifications that include most types of real property maintenance, repair, and construction work. The Assistant Secretary of the Air Force for Acquisition's Operational Contracting Division (SAF/AQCO) identified a number of failed SABER contracts. The problem statement designed for this research effort was: There are a large number of SABER contractors that are failing during the performance period on their SABER contracts. SAF/AQCO is trying to …
Influence Of Anonymity In A Group Problem-Solving Environment, Robert A. Sylvester
Influence Of Anonymity In A Group Problem-Solving Environment, Robert A. Sylvester
Theses and Dissertations
A group support system (GSS) uses a combination of networked personal computers, software that collects, manipulates, and aggregates member's individual input, and human facilitation to improve the group decision-making process. Prior GSS research has found that content and process anonymity influence problem solving groups. However, previous studies report mixed results on which levels of anonymity positively influence group performance. This thesis looked at content and process anonymity using four treatments to explore possible explanations for the mixed results found in previous GSS research. The study examined numerous theories including anonymity, identification, social loafing, and social comparison. An experiment was developed …
Relating Initial Budget To Program Growth With Rayleigh And Weibull Models, Eric J. Unger
Relating Initial Budget To Program Growth With Rayleigh And Weibull Models, Eric J. Unger
Theses and Dissertations
Previous research on completed defense R&D shows that contract expenditures can be fit well with a Rayleigh model. With fixed outlay rates, as prescribed by the OSD comptroller, the budget profile must have most of the funds in the early years to produce Rayleigh-distributed expenditures. R&D programs with more delayed funding profiles may also produce expenditures that a Rayleigh model fits through schedule slips and cost overruns. This research tests how well the initial funding profile produces Rayleigh-distributed expenditures that can be related to the program's final cost overrun and schedule slips. Based only on the initial budget profile, we …
A Delphi Assessment Of The Digital Rosetta Stone Model, Don M. Kelley
A Delphi Assessment Of The Digital Rosetta Stone Model, Don M. Kelley
Theses and Dissertations
Information that is stored digitally can only be used if it can be retrieved and interpreted. if the methods to retrieve the information are lost, it may be difficult, if not impossible, to recreate them. The knowledge to interpret the bitstream is also at risk. The Digital Rosetta Stone (DRS) Model was developed as a framework for capturing and maintaining the methods necessary to retrieve and display digital information stored on obsolete media or using obsolete software. However, this conceptual model had not yet been assessed by the community of professionals for its practical efficacy. This thesis began the assessment …
Gss Technology As A Moderator Of Influence And Perceived Expertise, Kevin V. Thompson
Gss Technology As A Moderator Of Influence And Perceived Expertise, Kevin V. Thompson
Theses and Dissertations
Group Support System (355) research has found this content and process anonymity influence problem solving groups. However, previous studies report mixed results on how OSS technology changes social influence processes and recognition of expertise which affect group performance. This thesis explored content and process anonymity's affect on influence and perceived expertise using three treatments to derive possible explanations for the mixed results found in previous GSS research. The study developed a theoretical model of influence, perceived expertise, and performance. Using structural equation modeling the study tested the relationships between expertise and participation rates, and overall group performance. An experiment was …
The Effect Of External Safeguards On Human-Information System Trust In An Information Warfare Environment, Gregory S. Fields
The Effect Of External Safeguards On Human-Information System Trust In An Information Warfare Environment, Gregory S. Fields
Theses and Dissertations
This research looks at how human trust in an information system is influenced by external safeguards in an Information Warfare (1W) domain. Information systems are relied upon in command and control environments to provide fast and reliable information to the decision-makers. The degree of reliance placed in these systems by the decision-makers suggests a significant level of trust. Understanding this trust relationship and what effects it is the focus of this study. A model is proposed that predicts behavior associated with human trust in information systems. It is hypothesized that a decision-maker's belief in the effectiveness of external safeguards will …
Award Term Incentive Contracting: An Investigation Of United States Air Force Strategic Purchasing, Rachael A. Harris
Award Term Incentive Contracting: An Investigation Of United States Air Force Strategic Purchasing, Rachael A. Harris
Theses and Dissertations
This research explored implementing a best commercial practice of establishing strategic purchasing relationships within the Department of Defense (DOD) procurement environment. The research was sparked by Air Force Material Command's (AFMC) instituting a commercial style acquisition strategy using an award term incentive on several programs. The award term incentive provides for extensions or reductions to the term of the contract based on contractors' level of performance. Forthcoming implementation of Air Force FAR supplement 5317.7X Incentive Term Extension, will likely increase the number of acquisitions using an award term incentive. Research findings indicate that management should consider expanding the AFMC award …

Combining Activity-Based Costing With The Simulation Of A Cellular Manufacturing System, Paul Savory, Robert Williams, Rodney Rassmuseun
Combining Activity-Based Costing With The Simulation Of A Cellular Manufacturing System, Paul Savory, Robert Williams, Rodney Rassmuseun
Department of Industrial and Management Systems Engineering: Faculty Publications
This paper presents an integrated simulation and activity-based management approach for determining the best sequencing scheme for processing a part family through a manufacturing cell. The integration is illustrated on a loop or U-shaped manufacturing cell and a part family consisting of four part types (A, B, C, and D). Production requirements for the cell demand that part batches be processed one type at a time. For example, all part A’s are processed until weekly demand is met, then part B’s, etc. The objective of this example is to determine the best part sequence (e.g., ABCD, DCBA or CABD). In …
Combining Activity-Based Costing With The Simulation Of A Cellular Manufacturing System, Paul Savory, Robert Williams, Rodney Rassmuseun
Combining Activity-Based Costing With The Simulation Of A Cellular Manufacturing System, Paul Savory, Robert Williams, Rodney Rassmuseun
Department of Industrial and Management Systems Engineering: Faculty Publications
Discrete-event simulation is one of the most effective techniques for analyzing a manufacturing system. Unfortunately, little attention is given to using simulation models to estimate the economic impact of a proposed system configuration. This paper defines how activity-based costing (ABC) concepts can be incorporated into a discrete-event simulation model. Special emphasis is on demonstrating how decision making can be aided by having the simulation create a detailed “Bill of Activity” describing costs associated with manufacturing a part. The integration of ABC and simulation is illustrated by evaluating the impact of a proposed manufacturing cell configuration. The additional costing information aids …
A Process Theory Of Competency Rallying In Engineering Projects, Bernhard R. Katzy, Kevin Crowston
A Process Theory Of Competency Rallying In Engineering Projects, Bernhard R. Katzy, Kevin Crowston
School of Information Studies - Faculty Scholarship
Firms face an environment changing at an increasingly rapid pace. Market opportunities in particular can arise and disappear in a short time. Unfortunately, the speed with which organizations can adapt their strategies and competencies to meet these opportunities remains limited. We argue that firms can address these individual limitations by cooperating with others for access to market opportunities and needed competencies. In this paper, we present a process theory of how a network of firms can reliably engineering and deliver products in the face of rapid market changes. In this theory, the success of the network is predicated on 1) …
