- Please can u answer this true and false 1. The design capacity is often lower than the effective capacity. 2. To improve efficiency firms should train employees and correct quality problems. 3. Mass Customization processes are low volume and low variety 4. Process Strategies have long-term effects on efficiency and production flexibility 5. Continuous processes are high volume but a low variety of products. 6. Modules are parts or components of a product previously prepared, often in a continuous process. 7. Effective capacity is the number of units a facility can hold, receive, store, or produce ha pers 8. Utilization is the theoretical maximum output of a system in a given period under idea conctionsCalculate Lead Time Williams Optical Inc. is considering a new lean product cell. The present manufacturing approach produces a product in four separate steps. The production batch sizes are 66 units. The process time for each step is as follows: Process Step 1 7 minutes Process Step 2 5 minutes Process Step 3 9 minutes Process Step 4 4 minutes The time required to move each batch between steps is 16 minutes. In addition, the time to move raw materials to Process Step 1 is also 16 minutes, and the time to move completed units from Process Step 4 to finished goods inventory is 16 minutes. The new lean layout will allow the company to reduce the batch sizes from 66 units to 4 units. The time required to move each batch between steps and the inventory locations will be reduced to 3 minutes. The processing time in each step will stay the same. Determine the value-added, non-value-added, and total lead times, and the value-added ratio under the present and proposed production…(Electro Corporation) The Electro Corporation manufactures two electrical products: air conditioners and fans. The assembly process for each is similar in that both require a certain amount of wiring and drilling. Each air conditioner takes 3 hours of wiring and 2 hours of drilling. Each fan must go through 2 hours of wiring and 1 hour of drilling. During the next production period, at most 240 hours of wiring time are available and at most 140 hours of drilling time may be used. Each air conditioner sold yields a profit of $25. Each fan assembled may be sold for a $15 profit. Formulate an LP of this product mix problem to find the best combination of air conditioners and fans for the highest total profit.max pX 1 + qX 2 (Total profit) s.t. aX 1 + bX 2 u (Wiring) cX 1 + dX 2 v (Drilling) X 1, X 2 0(Hint: Let X1 = number of air conditioners and X2 = number of fans)
- a chain saw requires 4 hours of assembly and wood chipper 3 hours.A maximum of 36 hours of assembly time is available.The profit is $150 on a chain saw and 220 on a chipper.How many of each should be assembled for maximum profit?Assuming your company is producing Apple and Samsung phone cases. It is required to process in the assembly and paint shops to make either phone case. It takes 1/60 of a day and 1/40 of a day to paint an Apple case and a Samsung case in the paint shop, respectively. It takes 1/50 of a day to assemble either type of case in the assembly shop. An Apple phone case and a Samsung phone case yield profits of $300 and $220, respectively, per case sold. What is a maximum-profit daily production plan for your company?Courtesy Calls makes telephone calls for businesses and charities. A profit of $0.50 is made for each business call and $0.40 for each charity call. It takes 4 min (on average) to make a business call and 6 min (on average) to make a charity call. If there are 240 min of calling time to be distributed each day, how should that time be spent so that Courtesy Calls makes a maximum profit? What changes, if any, occur in the maximum profit and optimal production policy if they must make at least 12 business and 10 charity calls every day?
- A pharmaceutical company creates a compound with a four-stage process: Some of the resources have partial yields: 15 percent of material is discarded after the Acid step and 40 percent of the material is discarded after the separation step. The capacities of the last three steps are as follows: Acid: 240 kg/hour Reaction: 200 kg/hour Separation: 200 kg/hour (a) What is the yield of the Heat resource? (Round your answer to 2 decimal places; do not convert yields into percentage) (b) What is the yield of the Acid resource?

From past experience, Fruit knows that 80% of all batches contain 10% (1 out of 10) defective chips, and 20% of all batches contain 50% (5 out of 10) defective chips. If a good (that is, 10% defective) batch of chips is sent to the next stage of production, processing costs of $4000 are incurred, and if a bad batch (50% defective) is sent on to the next stage of production, processing costs of $16000 are incurred. Fruit also has the alternative of reworking a batch at a cost of $4000. A reworked batch is sure to be a good batch. Alternatively, for a cost of $400, Fruit can test one chip from each batch in an attempt to determine whether the batch is defective. QUESTIONS 1.Determine a strategy so Fruit can minimize the expected total cost per batch. 2.Compute the EVSI and EVPI.A company produces two products: A and B. Prod-uct A sells for $11 per unit and product B sells for $23 per unit. Producing a unit of product A requires two hours on assembly line 1 and one unit of raw ma-terial. Producing a unit of product B requires two units of raw material, one unit of A, and two hours on as-sembly line 2. On line 1, 1300 hours of time are avail-able, and 500 hours are available on line 2. A unit of raw material can be bought (for $5 a unit) or produced(at no cost) by using two hours of time on line 1.a. Determine how to maximize profit.b. The company will stop buying raw material whenthe price of raw material exceeds what value? (UseSolverTable.)
- Cablesplice, Inc.'s manufacturing process consists of five steps: making con- ductors, adding insulation, adding sheathing, irradiation, and printing and coil cuttingUnits are measured in meters.
