A pharmaceutical company keeps detailed documentation of its inventory. The company replenishes its inventory whenever the inventory level falls below a certain limit and there is a threat of a stockout. This company is most likely using a __________ model. • fixed–time period • regression • single-period • fixed–order quantity Identify a true statement about water transportation mode. • It can handle a high capacity of materials. • Moving high volumes of products is costly. • Fast transit times can be achieved in this mode of transportation. • It is a highly specialized mode of transport limited to the delivery of gases. 8 Define customer order decoupling point. • It is the positioning of inventory in a supply chain. • It illustrates the method by which a company’s strategy is delivered through a set of supporting activities. • It is the time required to attend a customer order. • It involves the analysis of current business data to better solve business problems using mathematical calculations. 9 __________ are used for decisions that are related to aggregate and strategy demand. • Process assessments • P-models • Strategic forecasts • Periodic review systems 10 __________ is the design, operation, and improvement of the processes that create and deliver a company’s essential products and services. • Inventory control • Operations and supply chain management • Aggregate sales and operations planning • Product routing 11 __________ refers to the integrated activities designed to achieve high quality and high levels of production with minimal inventories of raw materials and to eliminate wastes. • The Shingo system • Lean production • Process mapping • Kanban system 12 A shopkeeper purchases raw materials to manufacture souvenirs for a local event that happens once every five years. In this case, identify the model that the shopkeeper is most likely to use to maintain stock. • Lot sizing model • Fixed–time period model • Single-period model • Fixed–order quantity model 13 In a __________, the product remains in a specific location and the equipment, labor, and material required for the product are gathered to the specific location. • manufacturing cell • functional layout • project layout • workcenter 14 Define waste reduction. • It is the optimization of the rate at which cash is generated by production through sales. • It is the process of combining the concept of cross-docking and consolidation. • It is the elimination of non–value-adding activities and the optimization of value-adding activities that are part of a process. • It is the integration of activities to increase the customer value of a process. 15 __________ shows the relationship between the total number of units produced and the unit production tim • Cycle time • A learning curve • Service rate • A Poisson distribution 16 Identify the true statements about the learning curve theory. • In a learning curve, the time for task completion will increase each time the task is undertaken. • A drawback of the learning curve theory is that the performance can be measured only in terms of time per unit. • It assumes that the unit time for a task will decrease at a decreasing rate. • In a learning curve, the reduction in time will be unpredictable. 17 Define preventive maintenance. • It is the grouping of similar parts and processes into a specialized workcell. • It is the periodic inspection and repair of equipment to avoid breakdowns. • It is the emphasis of getting a product or a process right the first time. • It is the improvement that stems from both a person’s experience and the changes in equipment, product design, and administration. 18 __________ Utilization is the ratio between the actual amount of time a resource is activated for and the total amount of time the resource is available for use. • Lead time • Service rate • Utilization • Pacing 19 __________ involves testing random samples of the end product from a process to determine if the process is churning out items within the predetermined range. • Organizational learning • Event simulation • Statistical process control • Cyclical strategic scheduling 20 __________ is responsible for scheduling, dispatching, monitoring, and regulating production on the shop floor. • P-model • Manufacturing execution system • ABC classification • Enterprise resource planning 21 __________ is the characteristics of a product in terms of quality that are sorted as either conforming or nonconforming to specification. • A throughput rate • A learning curve • The capability index • An attribute 22 Define lead time. • It is the time required to produce a variety of products typically at lower volume levels. • It is the time required to attend to a customer order. • It is the time required to position inventory in the supply chain. • It is the time required to achieve high customer service with minimum levels of inventory investment. 23 __________ determines the amount of inventory, which includes parts, components, and materials, necessary to produce a product. • Material requirements planning • Break-even analysis • Dynamic programming • GAP analysis 24 Identify a true statement about services. • A service has very limited or no customer interaction. • A service is a tangible process. • A service is inherently heterogeneous • A service has physical dimensions. 25 According to Goldratt’s definition, __________ is the rate at which cash is generated by production through sales. • productivity • cash flow • expediting • throughput 26 The manager of a shop floor schedules production based on the equipment that are used in the process as a key resource. In this case, the manager is most likely using a __________. • labor-limited process • machine-limited process • backward scheduling • forward scheduling 27 Identify an advantage of pure projects. • Team members have authority over the project. • Duplication of resources is eliminated. • Organizational goals and policies are upheld. • Team pride, motivation, and commitment are high. 28 A manufacturing firm efficiently assembles an airplane by bringing all the necessary raw materials, parts, and equipment to a central location. This scenario illustrates a __________. • workcenter • functional layout • project layout • manufacturing cell 29 Rachel performs an analysis in which she analyzes the performance of the clients of her organization relative to the expectations of the client’s customers. In this scenario, Rachel is most likely using a __________. • Pareto analysis • bar chart • Gantt chart • gap analysis 30 Define synchronous manufacturing as stated by Goldratt’s theory. • It is a production process organized to achieve the goals of the firm. • It is the optimization of the rate at which cash is generated by production through sales. • It is an integrated set of activities designed to achieve high quality and high levels of production with minimal inventories of raw materials. • It is a production process in which machines are the critical resource used for scheduling.
