We develop a search-theoretic model of the product market that generates price dispersion across and within stores. Buyers differ with respect to their ability to shop around, both at different stores and at different times. The fact that some buyers can shop from only one seller while others can shop from multiple sellers causes price dispersion across stores. The fact that the buyers who can ...

This paper provides a simulation model to study the effect of the work-in-process control on due date performance in job shop environment. The due date performance is measured by both the number of tardy jobs and the total tardiness. The simulation runs include different shop configurations (flow shop and general job shop), workloads and sequencing rules. As expected, the results reveal that du...

Where households across income levels shop for food is of central concern within a growing body of research focused on where people live relative to where they shop, what they purchase and eat, and how those choices influence the risk of obesity and chronic disease. We analyzed data from the National Household Food Acquisition and Purchase Survey (FoodAPS) using a conditional logit model to det...

In a shop floor of the industry, the routings which are based upon the jobs that need to be processed on different machines are one among the major activities and therefore the resource requirements are not based upon the quantity as in a flow shop but rather the routings for the products being produced. However, both job shop and flow shop production cope with a scheduling problem to find a fe...

The underlying model of an electronic payment system consists of three parties: a bank, a customer, and a shop. There are three different types of transactions within the system: withdrawal involving the bank and the customer, payment involving the customer and the shop, and deposit involving the shop and the bank. The customer's account is debited during withdrawal, and the shop is credited du...

This paper describes the radiotherapy patient scheduling problem of minimising waiting times. Like many other service industry problems, radiotherapy patient scheduling may be solved by first modelling and formulating it into a shop scheduling problem. Over the years, these shop scheduling models have been researched and solved using various approaches. This paper typifies radiotherapy patient ...

Abstract Windshield glasses of Maruti Alto 800 (A800), Hyundai i20 (H20), and Suzuki Eeco (SE) are taken from an automotive repair shop for investigating their physical, optical, mechanical properties to check durability. These amorphous, which is confirmed by X-ray diffraction (XRD). Energy dispersive spectroscopy confirms that the windshield contain SiO 2 , Na O, MgO, CaO, Al O 3 K in variabl...

The Tricked-Out Virtual Body Shop is an extrapolation of engineering curriculum design activities that have successfully engaged African-American students. Declining enrollment among underrepresented African-American students in STEM may be related to negative perceptions of science, technology, engineering, and mathematics (STEM). This concept is designed to directly engage students in constru...

We developed a strategic-planning model to optimize BMW’s allocation of various products to global production sites over a 12-year planning horizon. It includes the supply of materials as well as the distribution of finished cars to the global markets. It determines the investments needed in the three production departments, body assembly, paint shop, and final assembly, for every site and the ...
