Why or why not?Of the five factors listed in this section, which is most important in choosing the plant location?,Production anOperations,Production ProcessesThere are several different processes thatmanufacturers use to produce goods.The manufacturing process means phySiCally orchemically chan

23、ges to materials.,The,process puts together components to,make a product.These two processes are called synthetic systems.,Production and Operations,Production ProcessesSynthetic ProcessThe synthetic process either converts raw materials into other products (manufacturing process) or combine raw mat

24、erials or parts into a finished prodUCt (assembly process).Analytic ProcessAn analytic process breaks down raw materialsinto components to extract other products.,Production and Operations,Production ProcessesProduction processes are either continuous orintermittent.Continuous ProcessA continuous pr

25、ocess (:f_T ?f0T) is one in which massive production is carried out over time.It is a flow prodUCtion method used to manufacture, produce, or process materials without interruption. Production workers in continuous production commonly workin rotating shifts.,Production and Operations,Production Proc

26、essesIntermittent ProcessAn intermittent production process uses the customers orders to produce goods. The process is not continuous.Manufacturers of custom-designed (J/* j$) furniture would use an intermittent process. Computers, robots, and flexible manufacturing processes allow firms to turn out

27、 custom-made goods.,Production and Operations,Production ProcessesQuestions for DiscussionCan you explain the differences among the following concepts: manufacturing process, assembly process, analytic process,continuous process, and intermittent process? Give examples to illustrate the production p

28、rocesses.,Production and Operations,Material, Purchasing and Inventory ControlMaterials ManagementMaterials are inputs to production ormanufacturing.Materials requirements planning (MRP) is a computer-based system that uses sales forecasts to make sure that needed parts and materials are available a

29、t the right place and the right time.,Production and Operations,Material, Purchasing and Inventory ControlMaterials ManagementMRP II, an advanced version of MRP that allows plants to include all the resources involved in the efficient making of a prodUCt, including projected sales, personnel, plant

30、capacity, and distribution limitations.MRP II is called, in contrast, manufacturingresource planning (j$=_+, ) because the planning involves more than just material requirements.,Purchasing,d MaterialsIVlanagement,Production and Operations,Material, Purchasing and Inventory ControlMaterials Manageme

31、ntEnterprise resource planning (ERP) (k?kt+ ), the latest version of MRP, is a computer- based production and operations system that links multiple firms into one integrated production unit.ERP is much more sophisticated than MRP IIbecause it monitors processes in multiple firms at the same time.,Pr

32、oduction and Operations,Material, Purchasing and Inventory ControlMaterials ManagementSuch programs will link suppliers, manufacturers, and retailers in a completely integrated manufacturing and distribution system that will be constantly monitored for the smooth flow of goods from the time that the

33、y are ordered to the time they reach the ultimate consumer.,Production and Operations,Material, Purchasing and Inventory ControlPurchasingPurchasing is the function in the company that searches for quality material resources, locates the best suppliers, and negotiates the best price for quality good

34、s and services.The relationship between suppliers and manufacturers is much closer, with suppliersoften locating their facilities near themanufaCturer.,Production and Operations,Material, Purchasing and Inventory ControlPurchasingThe purchasing department is responsible for locating such suppliers,

35、negotiating long-term contracts with them with the best price.,Production and Operations,Material, Purchasing and Inventory ControlInventory ControlInventory refers to a list of goods and materialsheld available in stock.Manufacturing organizations usually divide their inventory into three parts:Mat

36、erials and components scheduled for usein making a product;Materials and components that have beguntheir transformation to finished products;Finished products that are ready for sale tocustomers.,rouction and Operations,Material, Purchasing and Inventory ControlInventory ControlOne major cost of pro

37、duction is holding parts,motors, and other items in warehouses.To cut such costs, the Japanese implemented a concept called just-in-time (JIT) inventory control.The idea is to have suppliers deliver their products “just in time” to go on the assemblyline. A minimum of inventory is kept on thepremise

38、s.,Production and Operations,Material, Purchasing and Inventory ControlInventory ControlHow JIT works?A manufacturer sets a production scheduleusing ERP and determines what parts andsupplies will be needed. It then informs its suppliers of what will be needed. The suppliers must deliver the goods ju

39、st in time to go on the assembly line.* A bare minimum must be kept in storage justin case the delivery is held up for some reason.,Production and Operations,Material, Purchasing and Inventory ControlInventory ControlThe latest version JIT II: there is much more sharing of information. An employee f

40、rom the supplier may work full-time at the buyers plant handling the smooth flow of materials.ERP and JIT systems make sure the rightmaterials are at the right place, at the right time, and at the lowest COSt to meet both customer and production needs.,Production and Operations,Material, Purchasing

41、and Inventory ControlQuestions for DiscussionWhat is enterprise resource planning? What are its advantages compared to MRP and MRPDescribe some advantages and disadvantages of just-in-time inventory control. How would you, as a manager in a large firm with many plants, implement a JIT system?,Produc

42、tion and Operations,Controlling Production: SchedulingA schedule is a representation of the timenecessary to carry out a particular task.A job schedule shows the plan for a particular job. It is created through reviews which determine the method and time required.,Production and Operations,Controlli

43、ng Production: SchedulingScheduling can have a major impact on the productivity of a process. The purpose of scheduling is to minimize the production time and costs, by telling a production facility what to make, when, with which staff, and on which equipment.A master production schedule (. !.) will

44、 show when the manager plans to produce each product and in what quantities.,Production and Operations,Controlling Production: SchedulingSchedulingIn preparing a production schedule, attention needs to be paid to:*delivery dates (when finished prodUCts are due);job schedules for each relevant produc

45、tion task; *capacities of production sections or departmentsinvolved;efficienCy of these prodUCtion seCtions ordepartments; *planned holidays.*anticipated sickness/absenteeism/training;*availability of raw materials, components and packaging.,Production and Operations,Controlling Production: Schedul

47、 Production: SchedulingPERT ChartsThe critical path (VIII?)is the sequenceof tasks that takes the longest time to complete. This word critical is used in this term because adelay in the time needed to complete this path would cause the project or produCtion line to be late. .,(1 week),Production and

To calculate that

49、number, you add the week it takes to pick a star and a song, to the four weeks to design a set, the two weeks to pUrChase set materials, the six weeks to construct the set, the week before rehearsals, and the final week when the video is made. Thats the critical path.,Production and Operations,Contr
