Q

Customers’ production roles.

A

Both uncertainties are related to customer involvement in services. Since customers usually help in creating the service, the outcome can vary depending on how well the service provider does their job.

Q

Underutilization and overutilization

A

there is debate about using extra capacity and stock. Traditional methods keep extra stock and deliver early to prevent production issues.

33
Q

uniform plant loading

A

Smoothing the production flow helps reduce the ups and downs that usually happen when the schedule changes.

34
Q

Kanban

A

means “sign” or “instruction card” In Japanese. In a paperless control system, containers can be used instead of cards.

35
Q

Setting up a Kanban control system requires determination of the

A

supply chain partners, all processes and all customers so that three sustainability dimensions (economic, environmental and social) are achieved in the best possible way.

36
Q

Kanban formula

A

’
k= expected demand during lead time + safety stock / size of the container

37
Q

A

is defined as the art science of obtaining, producing and distributing material and product in the proper place and in proper quantities.

38
Q

International logistics

A

refers to managing these functions when the movement is on global scale.

39
Q

Transportations modes

A

Most companies use multiple types of transportation, not just one. Standardized containers make it easy to move products between trucks, planes, and ships

40
Q

Warehouse Design

A

Special consolidation warehouses are used when shipments from various sources are pulled together and combined into larger shipments with a common destination.

41
Q

Cross-docking

A

A method where large shipments are divided into smaller ones for local delivery instead of sending bigger shipments

42
Q

Hub and Spoke systems

A

These combine consolidation and cross-docking, with a warehouse acting as a “hub” for sorting goods.

43
Q

Plant Location Methods

A

Choosing a location for a plant depends on the business type and competition

44
Q

common plant locatoon methods

A

● Factor Rating Systems: Weighing factors like cost, labor, and access.
● Transportation Method of Linear Programming: Optimizing shipping costs.
5

● Centroid Method: Finding the best location based on distances and demand

45
Q

Transportation Method

A

A linear programming technique used to solve problems of transporting goods from multiple sources to multiple destinations efficiently.

46
Q

Centroid Method:

A

A tool for finding the best location for a single facility by considering existing locations, distances between them, and the volume of goods to be transported.

47
Q

MRP

A

is based on dependent demand, it is the demand caused by the demand for a higher-level item.

48
Q

Master Production Scheduling

A

Still further down the disaggregation process is the MRP program, which calculates and schedules all raw materials, parts, and supplies needed to make the product

49
Q

Time fences

A

The purpose of time fences is to maintain a reasonably controlled flow through the production system.

50
Q

Available to promise

A

A feature of MRP systems that identifies the difference between the number of units currently included in the master schedule and the actual (firm) customer orders.

51
Q

Bill of Materials (BOM)

A

A detailed list that describes a product, including all materials, parts, and components, the quantity of each, and the order in which they are used to make the product.

52
Q

Inventory Records

A

A detailed file that tracks the status of inventory over specific time periods. The MRP system uses this information to manage inventory levels and plan product

53
Q

Lot-for-Lot (L4L)

A

A common method where planned orders match exact net requirements. It produces only what’s needed each period, avoids carrying inventory, and minimizes holding costs but ignores setup costs and capacity limits.

54
Q

Economic Order Quantity (EOQ):

A

A model that calculates the ideal order size based on total annual demand, setup or order costs, and annual holding costs. However, EOQ lot sizes may not align perfectly with the number of periods required.

55
Q

Least Total Cost (LTC)

A

A lot-sizing method that compares carrying costs and setup costs for different lot sizes, choosing the size where these costs are closest to being equal.

56
Q

Least Unit Cost (LUC)

A

A lot-sizing method that adds ordering and inventory carrying costs for each lot size, then divides by the number of units in the lot. The lot size with the lowest cost per unit is chosen.

57
Q

Inventory Management

Managing inventory means controlling stocks of items or resources in an organization.

58
Q

Single-Period Model

A

For one-time purchases.

59
Q

Q

Fixed-Time Period Model

A

Orders at regular intervals, quantity varies.

61
Q

inventory costs

A
  1. Holding Costs: Includes storage, insurance, and depreciation.

  • Single-Period Systems: For one-time purchases.
  • Multi-Period Systems: Ensure availability throughout the year. Includes:
  • Fixed-Order Quantity (Q-Model): Orders when stock reaches a specific level. - Fixed-Time Period (P-Model): Orders at regular intervals
64
Q

Inventory Turnover

A

Formula: Inventory Turnover = Cost of Goods Sold / Average Inventory Value Purpose: Tracks how often inventory is replaced annually.

65
Q

A

The amount on hand plus on-order minus backordered quantities

Fixed-Time period System

A

In a fixed-time period system, inventory is counted only at a particular time, such as every week or every month.

67
Q

Price-Break Model

A

Optimize the order size when prices vary with quantity. - Steps:
Calculate the Economic Order Quantity (EOQ) for each price level. Compare costs and choose the lowest-cost quantity.
