A Neural Network For Collaborative Forecasting, Abdulrahman M. Enani Dec 2016

A Neural Network For Collaborative Forecasting, Abdulrahman M. Enani

Masters Theses

As the supply chain activities’ backbone, demand forecasting must be accurate. This paper proposes an artificial neural network forecasting model, which integrates and synchronizes shared information, such as sales or consumption rate among different partners, to improve the forecasting’s accuracy. This information sharing is part of the collaborative planning, forecasting and replenishment (CPFR) model, which is a supply chain model aiming to enhance the supply chain’s efficiency by jointly planning and forecasting between two or more supply chain partners that will be used as the base for production and replenishment activities. The model is validated using a tuna product sales …

A number of companies all over the world use salary administration systems that integrate work performance and potential for advancement to …


An Economic Evaluation Of A Biofuel Supply Chain Utilizing Multiple Feedstocks, Huaqi Zhang Dec 2016

An Economic Evaluation Of A Biofuel Supply Chain Utilizing Multiple Feedstocks, Huaqi Zhang

Masters Theses

Biomass is considered as one potential feedstock for biofuel production. However, the high cost of biomass-to-biofuel supply chain, attributed to biomass’s low bulk density and resulting harvest, storage, and transportation challenges, has been a major hindrance to the success of biomass-based biofuel industry. In addition, the issue of dry matter losses during storage for a feedstock has affected biomass quantity and quality if the feedstock is stored for several months after a single harvest in a year. One potential way to improve the economics of biomass supply chain is to reduce storage need and enhance the utilization of harvest equipment …


Simulation Of 48-Hour Queue Dynamics For A Semi-Private Hospital Ward Considering Blocked Beds, Wei Chen Mar 2016

Simulation Of 48-Hour Queue Dynamics For A Semi-Private Hospital Ward Considering Blocked Beds, Wei Chen

Masters Theses

This thesis study evaluates access to care at an internal medicine unit with solely semi-private rooms at Baystate Medical Center (BMC). Patients are divided into two types: Type I patient consumes one bed; Type II patient occupies two beds or an entire semi-private room as a private space for clinical reasons, resulting in one empty but unavailable (blocked) bed per Type II patient. Because little data is available on blocked beds and Type II patients, unit-level hospital bed planning studies that consider blocked beds have been lacking. This thesis study bridges that gap by building a single-stream and a two-stream …
