Linking equations for the analysis of a serial automated workstation system

Creator:: Nagarajan, Raghavendran D.
Abstract:: In this research, an analytical model for analyzing a production line consisting of a series of automated workstations with infinite buffers is developed. Automated workstations are assumed to have deterministic processing times, and independent exponentially distributed operating time between failures and repair times. The analytical model starts with existing results...

Multi-mode resource-constrained project scheduling problem with resource vacations and task splitting

Creator:: Buddhakulsomsiri, Jirachai
Abstract:: The research presented in this dissertation addresses the Multi-Mode Resource-Constrained Project Scheduling Problem (MMRCPSP) in the presence of resource unavailability. This research is motivated by the scheduling of engineering design tasks in automotive product development to minimize the project completion time, but addresses a general scheduling situation that is applicable...

Effectiveness of using two and three-parameter distributions in place of "best-fit distributions" in discrete event simulation models of production lines

Creator:: Sharma, Akash
Abstract:: This study presents the results of using common two or three-parameter "default" distributions in place of "best fit distributions" in simulations of serial production lines with finite buffers and blocking. The default distributions used instead of the best-fit distribution are chosen such that they are non-negative, unbounded, and can match...

Efficient heuristics for buffer allocation in closed serial production lines

Creator:: Vergara Arteaga, Hector A.
Abstract:: The optimal allocation of buffers in serial production systems is one of the oldest and most researched problems in Industrial Engineering. In general, there are three main approaches to the buffer allocation problem when the objective is to maximize throughput. The first is basically a systematic trial and error procedure...

General design rules for the allocation of buffers in closed serial production lines

Creator:: Staley, Dan R.
Abstract:: One of the classic problems in industrial engineering is the buffer allocation problem. The objective of the buffer allocation problem is to maximize some line output, typically throughput, through the allocation of buffers throughout the production line. Previous work in this area has focused on either determining general design rules...

Unconditional estimating equation approaches for missing data

Creator:: Lu, Lin
Abstract:: Missing data can lead to biased and inefficient estimation if the missing mechanism is not taken into account in the analysis. In this dissertation we propose two estimators that, under fairly general conditions, are asymptotically unbiased. The first proposed estimator assume the data are missing at random (MAR) and does...

Kenward-Roger approximate F test for fixed effects in mixed linear models

Creator:: Alnosaier, Waseem S.
Abstract:: For data following a balanced mixed Anova model, the standard Anova method typically leads to exact F tests of the usual hypotheses about fixed effects. However, for most unbalanced designs with most hypotheses, the Anova method does not produce exact tests, and approximate methods are needed. One approach to approximate...

Statistical aspects of two measurement problems : defining taxonomic richness and testing with unanchored responses

Creator:: Ritter, Kerry
Abstract:: Statisticians often focus on sampling or experimental design and data analysis while paying less attention to how the response is measured. However, the ideas of statistics may be applied to measurement problems with fruitful results. By examining the errors of measured responses, we may gain insight into the limitations of...

Establishment tolerance of six native sagebrush steppe species to imazapic (PLATEAU®) herbicide implications for restoration and recovery

Creator:: Bekedam, Steven
Abstract:: Scientists and land managers realize that integrated weed management (IWM) strategies are needed to attain successful and lasting improvements of weed infested landscapes. At this time no broadly reliable and environmentally safe IWM strategy has been developed to control exotic annual grasses that dominate many ecosystems of the northern Great...

Hydromulch tackifier and sucrose effects on microbial nitrogen and Bromus tectorum biomass

Creator:: Perkins, Lora B.
Abstract:: There is growing interest in using nutrient manipulations to control invasive plants such as Brornus lectorurn L. (cheatgrass). Both labile (sucrose) and recalcitrant (straw and sawdust) carbon sources are added to the soil surface to reduce plant available soil N via soil microbial immobilization. However, the application rates used in...
