PDF KES 40.00 picture_as_pdf EEE 407: Operational Research Second Semester Examination Operational research paper for the electrical and electronics engineering degree. Establishes the role of operational research in decision making and three components and three advantages of its models, then constructs the dual of a minimisation problem in three variables and determines graphically the range of optimality of the objective coefficients for a two-variable maximisation. Works a production problem through the graphical method: constraint lines, the feasible region, at least two profit lines with the direction of improvement of the objective, the optimal solution, and the equation of any redundant constraint. Solves two-person games, giving the range for the value of the game from a payoff matrix written for the second player and the values of two unknown entries that make a given entry a saddle point. Uses the simplex method on a three-variable maximisation with comment on the significance of the slack variables in the final solution, and minimises an objective under mixed constraints where no variable may fall below twenty. Explains degeneracy and sensitivity analysis, then a two-product mix bounded by sales share, daily raw material availability and usage rates: the optimal product mix, the worth per unit change in the availability of the raw material and its range of applicability, the revenue range over that feasibility range, and the effect of changing the maximum demand for one product by ten units. Closes on proportionality and additivity as the two properties of linear programming models, and on the project network for the construction of a new house from nineteen activities with their predecessors and durations to the critical path.

Discusses benefit cost ratio, marginal rate of substitution, net present value, average cost and returns to scale with diagrams, then works a policy case in which raising the price of a pack of cigarettes from two hundred to six hundred shillings moves the quantity of marijuana demanded from two thousand to eight hundred kilograms a day, to the cross price elasticity of demand and why the policy proves effective. Establishes the relationship between marginal cost and average cost and its significance, and two depreciation methods each with an advantage and a limitation. Continues with the effect of an import duty on cars on the equilibrium price and quantity of petrol, three policies a developing country may use on a balance of payments problem, and the floating against the managed exchange rate regime with a recommendation. Computes the marginal utility of two goods from a utility function at a given income and prices, defines supply with two factors that shift its curve left, and analyses a rent ceiling on urban housing. Selects between two projects across boom, normal and recession states from their probability distributions, finds equilibrium price and quantity from demand and supply functions, lists four monetary tools the central authority uses to control inflation, separates a monopoly from an oligopoly with examples, gives two determinants of elasticity of demand, works straight-line depreciation on equipment bought for a million shillings over an eight-year life with a twenty thousand salvage value, and traces the consequence for the oil and motor vehicle market when exporters raise the price of fuel. PDF KES 40.00 picture_as_pdf EBM 406: Hospital Engineering Management Second Semester Examination Hospital engineering management paper set for the degree of Bachelor of Science in Electrical and Electronics Engineering, sat on the first of February from half four to six in the evening, with question one compulsory at thirty marks and any two of the others at twenty. Question one explains how the World Health Organisation guidelines support hospital management and performance, discusses four health system objectives, identifies the features of a successful team, and sets out the role and responsibilities of professional registration bodies in Kenya with five such bodies. The remaining questions discuss four functions of the engineering department of a hospital that is at once commercial, industrial and residential; self-awareness through the Johari window diagram, with the ego as the driver of behaviour and three important ego states or behavioural patterns illustrated by examples; the legal liabilities and the laws governing medical issues in a hospital; the role of accreditation services in healthcare delivery and the implementation of the Joint Commission International standards, with how two legal provisions are applied within the hospital environment; and the scope and role of Food and Drug Administration regulation in the management of human health.
