Predecessor Activity J K L M N Length 7 4 4 5 5 J KM J M 8.1 Draw the network below. 8.2 How many ending activities are there? a) 1. b) 2. c) 3. d) 4. e) 5. 8.3 The perspective that says quality is based on the views of the customer or user is the a) bottleneck perspective. b) conformance perspective. c) theory of constraints. d) value perspective. 8.4 Which strategy for adding capacity adds new factories only once the demand had materialized for the product? a) Lag strategy b) Lead strategy c) Match strategy The following two questions invoke a service process that has a mean of 32 seconds with a standard deviation of 0.8 seconds, where the upper and lower specification limits for the process are 35 seconds and 29 seconds, respectively. 8.5 What is the process capability ratio for this process? a) 0.625 b) 0.80 c) 125 d) 3.00 none of these 8.6 Is this process capable of providing an acceptable level of quality (99.7% acceptable)? a) yes. b) no 8.7 The project shown below includes 10 activities (represented by the circles) with precedence relations as shown by the arrows. Activity times are not shown. What is the fewest number of activities that could be in the critical path? b) 4. c) 5. d) none of the above. 8.8 "Crashing a project is used to a) find the latest start and latest finish of a project. b) extend a project c) shorten a project 8.9 What percentage of points are expected to be between the upper and lower control limits? a) 50% b) 99% c) 99.7% d) none of the above 10 8.10 How many decisions are in the decision tree below? a) 2. b) 4. d) none of the above. $7000 0.6 Dem Increases 55000 07 Demand increase -$1000 03 Demand decreases 0.4 Dam Decreases Acop Loss Hire 2 workers 0.7 Demand increas -S3000 $4000 Hire 1 worker 0.3 Demand decreases -$300 Do Not Hire on Demand inea $800 03 Demand decreases -$500 8.11 There are two options for producing a product, A and B. Option B has a lower fixed cost than Option A, but a higher variable cost. If the fixed cost of Option A was increased, then the level of production that causes both options to have the same total cost would a) decrease b) increase c) stay the same
