VBK Fibreo Tech Industries was a manufacturer of fibre reinforced plastic (FRP) products for industrial and domestic applications. Despite being a new entrant, it managed to exhibit great performance and attract a loyal base of customers. This case brings to light the problem that the company was facing that is demand exceeding capacity. The protagonist of the case Madhav, the Production Manager, was tasked to solve the problem of “product mix”. He was in a dilemma on how to fulfill customer orders while minimizing losses for his company. He knew that while losses were inevitable in the current scenario, they could be minimized with appropriate planning. Students are expected to use data and facts from the case and exhibit to formulate LP, by identifying the objective function and the constraints. They are also encouraged to use MS-Excel solver to find the optimal product mix and understand the decision dependencies.

This case can be used to teach LP in an undergraduate/postgraduate-level course on operations research. Students are exposed to the creation of a mathematical model for optimization and along with devising the implementation plan.

Jetcon Corporation’s business model involved the importation of pre-owned cars from Japan for re-sale in Jamaica. It was a fiercely competitive business as there were over 100 companies involved in this sector. There was also a vibrant new-car sector. Jetcon focused on importing mid to low price Japanese pre-owned models, which were already common on Jamaican roads, and which would be affordable to the larger segment of buyers. Like most small businesses, it experienced difficulty raising financing in the amounts and cost that is required and this contributed to its decision to raise equity capital through an initial public offer. It was the first used-car dealer to list on the Jamaica Stock Exchange.

This case is suitable for final-year undergraduate students in finance. By that time they should already have been exposed to debt, equity and stock markets. It helps students to explore some of the issues involved in financing a company’s operations.
