- What is an Mechanical Plan?arrow_forwardThe ABC Company is planning a new product line and a new plant to produce the partsfor the line. The product line will include 8 different models. Annual production of eachmodel is expected to be 900 units. Each product will be assembled of 180 components.All processing of parts will be accomplished in the new plant. On average, 6 processingoperations are required to produce each component, and each operation takes an averageof 1 min (including an allowance for setup time and part handling). All processing operationsare performed at workstations, each of which includes a production machine and ahuman worker. The plant operates one shift.

- Answer the two connected questions (Task A-1 and A-2). Provided in the last part are the guides and examples: The process for large-scale manufacture of paper has been largely unchanged for the last 125 years. The pulp and paper industry today is highly capital intensive, and there is an ongoing drive towards process integration, thereby increasing the efficiency of utilization of available process resources. This paper deals with the Kraft process (see Fig. 1) though the general principles described can be extended to other pulping processes. As shown in Figure 1, five water sinks and four water sources are considered for in-plant water reuse/ recycle. Prior to water reuse/ recycle, the network requires a freshwater flow rate of 36,400 tonne/day and generates 37,186 tonne/day of wastewater (sum of the individual sink and source flow rates in Table 1).

Yet between 2002 and 2005 Hoover's market share dropped from 36 per cent to 13.5 per cent, Why? Because a futuristic looking and comparatively expensive rival product, the Dyson vacuum cleaner, had jumped from nothing to over 20 per cent of the market. In fact, the Dyson produce dales back to 1978 when James Dyson noticed how the air filter in the sprayfnishing room of a company when; he had been working was constantly clogging with powder particles (just like a vacuum cleaner bag clogs with dust).
