Graves, Gregory Howard (Texas A&M University, 2006-10-30)Physical security systems are intended to prevent or mitigate potentially catastrophic loss of property or life. Decisions regarding the selection of one system or configuration of resources over another may be viewed as ...
-
Ramachandran, Satheesh (Texas A&M University. Libraries, 1994)This dissertation develops an analysis of the stochastic behavior of a GI / GI / $infty$ queue. The GI / GI / $infty$ queueing system is analyzed under the steady state and transient operating conditions. System behavior ...
-
Yang, Xiaole (2011-08-08)In oil/gas and chemical industries, dynamics is one of the most essential characteristics of any process. Time-dependent response is involved in most steps of both the physical/engineering processes and the equipment ...
-
Barua, Shubharthi (2012-10-19)Oil/gas and petrochemical plants are complicated and dynamic in nature. Dynamic characteristics include ageing of equipment/components, season changes, stochastic processes, operator response times, inspection and testing ...
-
Wang, Shuwen (2009-05-15)Entry-time processes are finite-state continuous-time jump processes with transition rates depending only on the two states involved in transition, the calendar time, and the most recent arrival time, which is termed as ...
-
Hur, Sun (Texas A&M University. Libraries, 1993)The appropriateness of independence assumptions in queueing theory should be doubted at least in applications such as modem manufacturing or telecommunication systems. Simplifying independence assumptions may lead to a ...
-
Li, Bo (2016-06-28)I present three essays pertaining to the management of supply chain risks in this dissertation. The first essay and the second essay analyze supply chain risks from a financial perspective, while the third essay analyzes ...
-
Bakir, Niyazi Onur (Texas A&M University, 2004-11-15)This dissertation addresses the question of choosing the best information alternative in engineering decisions. The decision maker maximizes his expected utility under uncertainty where both the action he takes and the ...
-
Toptal, Aysegul (Texas A&M University, 2004-09-30)This dissertation takes into account the latest industrial trends in integrated logistical management and focuses on recent supply chain initiatives enabling the coordination of supply chain entities. The specific initiatives ...
-
Bily, Christopher (2012-10-19)Tradeoff studies are a common part of engineering practice. Designers conduct tradeoff studies in order to improve their understanding of how various design considerations relate to one another. Generally a tradeoff study ...
-
Gallart Hamilton, Diana (2017-01-19)The failure of protective systems can be catastrophic, and has its origin in management. Yet, most engineering works regarding protective systems focus on their physical components. Historically, protective systems have ...
-
Wang, Mengtian (2012-10-19)This study is aimed at exploring new process safety metrics for measuring the process safety performance in processing industries. Following a series of catastrophic incidents such as the Bhopal chemical tragedy (1984) and ...
-
Arreola-Risa, Antonio; Hamilton, Diana Gallart; Mannan, M. Sam; Nelson, Paul; Wortman, Martin A. (Mary Kay O'Connor Process Safety Center; Texas &M University. Libraries, 2019)Protective systems failure can be catastrophic, and originates in management failure. These systems rely on a document-based approach, which involves handling disjointed artifacts that are expensive to maintain and may ...
-
Park, Jee Hyuk (2009-05-15)A wager is a one time bet, staking money on one among a collection of alternatives having uncertain reward. Wagers represent a common class of engineering decision, where “bets” are placed on the design, deployment, and/or ...
-
Lee, Chong Ho (Texas A&M University. Libraries, 1994)In this research, we consider the problem of determining an optimal replacement policy for stochastically deteriorating systems for which only incomplete state information is available. When the deterioration is governed ...
-
Freeman, Thomas (Texas A&M University. Libraries, 1992)A new procedure, called the principal component method, is developed to handle the problem of data correlation in simulation output analysis. The method is derived from matrix diagonalization theorems, which allow for an ...
-
Prem, Katherine (2012-02-14)The occurrence of catastrophic incidents in the process industry leave a marked legacy of resulting in staggering economic and societal losses incurred by the company, the government and the society. The work described ...
-
Merriweather, Samuel P. (2013-08-06)Companies and organizations must make decisions concerning capital budgeting. Capital budgeting is a decision-making process that determines whether a firm should purchase equipment to be used on a long-term basis. The ...
-
Aral, Bahadir (2009-05-15)This dissertation focuses on developing inspection schedules to detect non-self- announcing events which can only detected by inspections. Failures of protective sys- tems ,such as electronic equipments, alarms and stand-by ...
-
Liu, Xingchu (Texas A&M University, 2006-08-16)In the context of supply contract design, the more powerful party has the lib- erty of withholding private information which also improves its bargaining power. Traditionally, the supplier (e.g., manufacturer) has been ...
