Based on higher education goals and the particular characteristics of operations research, we consider in this paper how to enhance operations research teaching by utilising contemporary teaching methodologies. Three possible approaches, concept mapping, group work and ‘inverse’ PBL (Problem Based Learning) are proposed, and corresponding new assessment schemes for ensuring these new methods’ m...

where the quantities involved in the above equalities are given as follows. Recall that AB denotes the (column induced) submatrix of A generated by B. (i) The basic solution x for the problem (P). (ii) The reduced costs r j := cj − (a.j) T y, where y is the dual basic solution, and a.j denotes the j column of A. (iii) The one-to-one mapping j() : {1, 2, . . . ,m} → B. Given i ∈ {1, 2, . . . ,m}...

We design and implement a dynamic program for valuing corporate securities, seen as derivatives on a firm’s assets, and computing the term structure of yield spreads and default probabilities. Our setting is flexible for it accommodates an extended balance-sheet equality, arbitrary corporate debts, multiple seniority classes, and a reorganization process. This flexibility comes at the expense o...

Thermal flowmeters are used more and widely in liquid flow measurement. In this paper, the mechanical shape of thermal flowmeter is designed, optimal installation position probe determined. aspect measurement mechanism research, three heating methods deduced: constant voltage method, current power method. After reasoning, method determined to be ideal, so selected heat speed-measuring experimen...
