As far as maintenance costs are concerned: O for high levels of maintenance commitment, breakdown maintenance costs exceed preventive maintenance costs. O for low levels of maintenance commitment, preventive maintenance costs exceed breakdown maintenance costs. preventive maintenance is always more economical than breakdown maintenance. breakdown maintenance is always more economical than preventive maintenance when the "full cost of breakdowns" is taken into consideration. O for low levels of mairtenance commitment, breakdown maintenance costs exceed preventive maintenance costs.

Assignment A company manufactures two products X and Y, which require the following resources. The resources are the capacities machine M1, M2, and M3. The available capacities are 50, 25, and 15 hours respectively in the planning period. Product X requires 1 hour of machine M2 and 1 hor of machine M3. Product Y requires 2 hours of machine M1, 2 hours of machine M2 and 1 hour of machine M3. The profit contribution of products X and Y are $ 5 and $ 4 respectively. 1- Formulate the above problem as (LP) and set up the standard linear programming model and represent the information in a table. 2- Solve the problem by using the graphic method. Does the problem represent a special case of linear programming ..Show this case? 3- Identify the feasibility area solution. 4- How many units of each type of product should be produced?

Hello please show your correct and complete solution with schematic diagram and assumptions. Thanks ASAP!

The annual demand for an item is 10,000 units. The unit cost is Rs. 100 and inventory carrying charges are 14.4% of the unit cost per annum. The cost of one procurement is Rs. 2000. The time between two consecutive orders to meet the above demand is _______ month

C)If both cyclists have 170 mm cranks on their bikes, what will be the mechanical advantage (considering only the movement of the feet with a constant force for walking and riding), in percent, that each rider will have achieved over walking the same distance? (This can be found by dividing the distance wallked by the distance the feet move in riding.)

5. Stress-strain calculation, heat transfer, and dynamic simulation are forms of: * Productivity efficiency Engineering analysis Documentation Data base optimization

what is material support in aviation maintenance?

2.1 You are tasked with planning of maintenance tasks at a water treatment facility. A critical pump has failed unexpectedly, causing significant downtime. Meanwhile, another pump of the same type has been operating without any issues. Illustrate using a diagram the planning process that highlights the difference between a maintenance task for an asset that has failed and a maintenance task that prevents failure from occurring. (6) 2.2 You are the working at a power generation plant. Over the past six months, the plant has experienced inconsistent performance from its critical assets, resulting in occasional production losses. The maintenance team recently implemented a new maintenance strategy to address this issue. Indicate the different methods to consider when assessing the effectiveness of the maintenance strategy. (3) 2.3 At a manufacturing facility, operators are primarily responsible for running production equipment, while the maintenance team handles all repairs and…
