Answer the question.

A manufacturing plant is planning to replace outdated equipment with more energy-efficient and environmental-friendly equipment. Two models are under consideration. Model A is sold for $159,000 and can produce at an optimum speed of 78 unit/hour. Model B is sold for the same price, but can produce at an optimum speed of 76 unit/hour. Model A requires 6 hours of maintenance for every 4300 units produced, while Model B requires 5 hours of maintenance for every 3300 units. The maintenance cost for both models is $100 per hour. The variable operating cost is $340 per hour for Model A and $290 per hour for Model B. Due to obsolete parts, there is a sunk cost of $2700 for model A and $1900 for Model B . If the price of the product is $150 per unit and the company expects to sell 145,000 units each year, which model should be selected?

2) Two alternative designs are under consideration for a tapered fastening pin. The fastening pins are sold for $0.80 each. Either design will serve equally well and will invole the same material and manufacturing cost except for the lathe and drill operations. Design A will require 16 hours of lathe time and 4.5 hours of drill time per 1,000 units. Design B will require 7 hours of lathe time and 12 hours of drill time per 1,000 units. The variable operating cost of the lathe, including labor, is $18.60 per hour. The variable operating cost of the drill, including labor, is $16.90 per hour. Finally there is a sunk cost of $5,000 for Design A and $9,000 for Design B due to obsolete tooling. a) Which design should be adopted if 125,000 units are sold each year? b) What is the annual saving over the other design?

A simple Zener diode shunt voltage regulator is to supply 12 V to a load which normally draws a load current which varies from 0 to 50 mA. The input voltage varies between 15 V and 18 V.

1.1 Calculate the maximum rated current value of a Zener device to be used.

1.2 Calculate the minimum power for the Zener that could be used safely.

1.3 If a 5 W rated Zener were to be used, calculate the range of possible RS. values and hence suggest a suitable standard E12 resistor value.

1.4 State four (4) conditions under which a Zener diode dissipates minimum power in a regulator circuit.

A proposed project is being procured through a Public – Private Partnership (PPP). In the PPP procurement process, two companies (the SPVs – special purpose vehicles) A and B with each having 0.5% chances of selection. The risks analysis document reveals that SPV ‘A’ has 0.4 risk of performance failure, whiles SPV ‘B’ has 0.3 risk of performance failure.

Using Decision Tree Analysis as as a project manager critically assess the options and advise on the best SPV to be chosen.
