supply chain management
| Question | Answer |
|---|---|
| TYPES OF LAYOUTS | fixed position office layout retail stores warehouse layout functionally-oriented/job shop layout product-oreinted/assembly line layout group technology/cellular manufacturing layout |
| FIXED POSITION LAYOUT | Large projects such as construction of buildings equipment and workers are moved to the project |
| OFFICE LAYOUT | group workers and equipment for flow of information. ex. most classrooms on 1st floor and starbucks on 2nd (bauer) |
| RETAIL STORES | emphasis is on MAXIMIZING CUSTOMER EXPOSURE TO PRODUCTS sales correlate with the exposure to products |
| WAREHOUSE LAYOUT | TRADE-OFF BETWEEN SPACE AND MATERIAL HANDLING |
| FUNCTIONALLY-ORIENTED/JOB SHOP LAYOUT | MINIMIZE the material handling cost or DISTANCE TRAVELED |
| PRODUCT-ORIENTED/ ASSEMBLY LINE LAYOUT | BALANCE THE TASKS AMONG WORK STATIONS ONO THE ASSEMBLY LINE AND THUS MINIMIZE THE IDLE TIME, PRODUCTION COSTS AND MAXIMIZIE EFFIECIENY |
| GROUP TECHNOLOGY/ CELLULAR MANUFACTURING LAYOUT | breaking jp process clusters into work cells such that EACH WORK CELL MAKES A FAMILY OF PRODUCTS |
| CRITERIA TO EVALUATE THE LAYOUT OF JOB-SHOP | LOAD: the degree of interaction b/t departments DISTANCE: distance b/t each pair of locations (vertical or horizontal) |
| HEURISTIC METHOD | method of grouping departments with heavy interactions b/t them close to each other in a rank ordered manner |
| REVERSE LOGISTICS | the flow of used products and returnable packaging back through the network |
| SYSTEMS APPROACH | views the process as integrated; decision at one point in the network can ripple throughout the system and impact subsequent points in the network |
| PIPELINES | intermodal freight transport: uses multiple modes of transportation containerazation: allows for the efficient interface and transfer of cargo, which results in faster deliver and lower total logistics costs |
| CROSS-DOCKING | avoids the placement of incoming merchandise into storage by processing items fro outbound shipment as they are received reduces inventory/distribuiton/warehouse costs reduce lead time use POS |
| TRANSSHIPMENT | made b/t different facilities at the same level in the supply |
| KEY ELEMENTS OF CLOSED-LOOP SUPPLY CHAIN | used product collection reverse logistics distribution |
| SHADOW (DUAL) PRICE | equal to the benefits you would obtain if you had more than one unit of that resource maximum amt. you would pay to purchase one resource |
| VENDOR MANAGED INVENTORY (VMI) | suppler is responsible for maintaing the inventory of the buyer |
| POINT OF SALE (POS) | an advanced IT that allow for continuos communication b/t pos, suppliers and warehouses |
| FUNCTIONS OF INVENTORY | -meet anticipated CUSTOMER DMANDS -decouple SUPPLIERS FORM PRODUCTION AND PRODUCTION FROM DISTIBUTION quantitiy discounts -inflation and upward price changes protect against dlivery vriations due to adverse conditions |
| ECONOMIC ORDER QUANTITY (EOQ) | gives the optimum lot size for a given set of costs. |
| 3 KEY INVENTORY MANAGAEMENT QUESTIONS | WHAT TO ORDER HOW MUCH TO ORDER WHEN TO ORDER |
| CYLE INVETORY | Cycle inventory: holding inventory save on set-up , transportation cost, & advantage of quantity discounts Average = Q/2 |
| TYPES OF INVENTORY | CLYCLE SAFTETY STOCK PIPELINE |
| REORDER POINT | under the deterministic world: ROP'S FORMULA EQUALS ONLY AT LT and supply -"probabilistic - safety stock must be introduced into the equation |
| PERIODIC REVIEW SYSTEM | review times are fixed while order quanties varyaccording to the inventory positioin |
| REORDER POINT SYSTEM | the inventory position is monitored continuously |
| VALID LP CONSTRAINT | having more than two decision variables makes it much more difficult to calulate the values ofor the allowable increase or allowable decrease for all resources |
| ASSUMPTIONS OF EOQ | demand is constant relevant costs are known and constant no quantity discounts LT for the receipt of orders is constant no shortages allowed |
| SAFETY STOCK EQUATION | SS = ZX(ÓDLT) SS = ZX STANDARD DEVIATION OF DEMAND DURING LEAD TIME |
| ROP | = DEMAND DURING LT - (DEMAND PER PERIOD) X (# OF PERIODS INT HE LT) ROP = DLT(AVG) + Z[Ó X √(LT)] |
