Developing A Model To Evaluate Maintenance Operations, Soundararajan Kannan

Masters Theses

Maintenance has become a prominent function in today's manufacturing environment. Tremendous efforts have been put into in developing different types of maintenance strategies for enhancing the performance of the equipment but very little has been done in actually streamlining maintenance activities. This refers to systematically evaluating and analyzing the non-value added activities within the maintenance function. One of the primary lean tools that can provide a different dimension in identifying and analyzing non-value added activities is Value Stream Mapping (VSM). However, the traditional VSM cannot be utilized "as is" because the maintenance activities do not completely correspond with VSM terminology. …

Development Of A Transportation Network Model For Complex Economic And Infrastructure Simulations, Paula S. Downes

Masters Theses

The intent of this effort is to add a transport network to an agent-based economic simulation model, thereby increasing the fidelity of the economic results reported. The majority of existing agent-based work regarding transportation infrastructures deals with traffic management and urban planning. However, little work has been done in modeling the transport system as a basic infrastructure dependency for an agent-based representation of the economy. In an agent-based modeling environment the transportation component derives its demand from the activities of the agents as they buy and sell goods which require transportation services. The Network Shipper agent was added to allow …

Utilizing Employee Stress To Establish Guidelines For Managing Personnel During Lean Transition, Nezhad Naim Jallal Hossiney

Masters Theses

Employee resistance has been one of the many primary obstacles during Lean execution. Employee stress is a principal outcome of resistance when implementing Lean systems. This research is directed towards finding the relationship between employee stress and Lean. The hypothesis states-Lean implementation increases employee stress.

The research methodology involves investigating employee stress during various phases of Lean. This research proposes three phases of Lean that are- Lean Introduction Phase, Lean Implementation Phase, and Lean Refinement Phase. Surveys are used to collect data for the study. Two questionnaires are used 1) Lean Environment Evaluation Profile (LEEP) 2) Work Stress Profile (WSP). …
