This essay analyses and evaluates critically Tesco’s current operations management. The essay discusses from 3 major perspectives namely, operations strategy, operations design and operations management. Firstly, it will show an introduction. The second section will analyze Tesco’s formats and international expansion at corporate strategy level. And then, based on the customer-centric conceptio...

PT. Merpati Maintenance Facility is a company engaged in aircraft maintenance services. This serves several types of such as Boeing and Airbus. In the process at Sidoarjo, to carry out every job it must be accordance with Task Card work made by PPC based on WO (Work Order), working task card, often lost creates data discrepancies, so does not know that matches card been done or not. With occurr...

In recent years, topics such as fraud detection and fraud prevention have received a lot of attention on the research front, in particular from payment card issuers. The reason for this increase in research activity can be attributed to the huge annual financial losses incurred by card issuers due to fraudulent use of their card products. A successful strategy for dealing with fraud can quite l...

In simple card games, cards are dealt one at a time and the player guesses each sequentially. We study problems where feedback (e.g., correct/incorrect) is given after guess. For decks with repeated values (as in blackjack suits do not matter), optimal strategy differs from “greedy strategy” (of guessing most likely round). Further, both greedy strategies far too complicated for real-time use b...

The TaqMan Array Card architecture, normally used for gene expression studies, was evaluated for its potential to detect multiple bacterial agents by real-time PCR. Ten PCR assays targeting five biological agents (Bacillus anthracis, Burkholderia mallei, Burkholderia pseudomallei, Francisella tularensis, and Yersinia pestis) were incorporated onto Array Cards. A comparison of PCR performance of...

The purpose of this experiment was to provide further information on how an individual's strategy and his performance are affected by increasing the amount of relevant or irrelevant information he receives. The subjects were sixty volunteers from ari -----u-n-dergYaduate course in educational psychology who were randomly assigned to one of six treatment groups. Each subject was told that he wou...

Billions of dollars of loss are caused every year due to fraudulent credit card transactions. The design of efficient fraud detection algorithms is key for reducing these losses, and more and more algorithms rely on advanced machine learning techniques to assist fraud investigators. The design of fraud detection algorithms is however particularly challenging due to non stationary distribution o...

In this paper, we study the dynamics of competition in the payment card market. This is done through a multi-agent based model, which captures explicitly the commercial transactions at the point of sale between consumers and merchants. Through simulation, we attempt to model the demand for payment instruments on both sides of the market. Constrained by this complex demand, a Generalised Populat...
