Final Solution
A robot is used for loading and unloading of parts to automated flexible machines. Loading
time is 1 minute; unloading time is 1.5 minutes; machining time 15 minutes; Robot travel time
between the machines including the inspection time is 3 minutes. Cost of robot C,=30 TL/Hour;
cost of machines C2=40 TL/Hour. How many machines (integer number) should be assigned
to the robot so that the total robot and machine costs per cycle are minimized?

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).

Four product groups have less than 5 years' experience, and 10 product groups have more. There are 24 engineers, each paid a salary of P60,000. Each engineer can provide 2,000 hours of service per year. The actual engineering usage was 46,000 hours. The standard is 58% of current practical activity capacity. Case 1: Calculate the (1) activity volume and (2) unused capacity variances for the engineering activity Case 2: Suppose the operational managers have selected some improvement measures that promise to reduce non-value-added activity usage by 40% in the following year.

- Task 1: Consider a simplified shape of a blood vein branching- similar to the Brachial vein. You like to determine whether this person is having a hypertension (high blood pressure) or a hypotension by determining the pressure in the main vein. Note that a nominal value for the normal pressure for that specific vein is 140 mmHg. If the found value is higher, we can consider the person to be hypertensive. Assume a blood density of 1050 [kg/m³] and a viscosity of 3.5 [Pa.s] Is this a hypertension case? (i.e., is the pressure in the main vein P1 > 140 mmHg? What is the classification of the flow in the main vein, rı = 7.5 mm? (laminar or turbulent)? Show your work.
