Some Questions about unit 10
1- What is (JIT) system based on?
This system based on purchasing materials only when they are actually needed without storage as an inventory
(Materials are purchased and transferred directly to production operations)
2- What is lean manufacturing?
Lean manufacturing expands the concept of just-in-time (JIT) The primary focus is on achieving more with less resources of (labour, equipment, space, etc).
It also focuses on providing customers with what they want, and achieving their expectations.
3- What are the five principles of lean manufacturing?
1) Value
2) Value stream
3) Flow and pull
4) Empowerment
5) Perfection
4- What is meant by kanban?
Kanban means ticket. Tickets control the production flow and parts flow, so that they are produced or obtained in the needed quantities at the needed times
5- What are the objectives of JIT?
* Higher productivity
* Reduced order costs
* Reduced carrying costs
* Faster and cheaper setups
* Shorter manufacturing cycle times
* Better performance and quality
6- What is Material Requirements Planning (MRP)?
MRP is a computerized system for transferring materials to the process of production based on a predetermined schedule
7- What is Manufacturing Resource Planning (MRP II)?
MRP II is a closed-loop manufacturing system that integrates all manufacturing business facets, including the following:
[Schedules, production, inventories, sales, and cash flows].
8- What is traditional ERP system?
The traditional ERP system is one in which subsystems share data of each other and coordinate their activities together. ERP is intended to integrate the systems of enterprise-wide information across the company, such as ( supply chain, accounting, treasury, etc.) by creating single database which is linked to all of the company’s applications.
9- What are the advantages of a Current ERP System?
* Reduced the costs of labor
* Lower costs of inventory
* Elimination of data centralization and data redundancy,
* management of liquid assets ina better way
* greater productivity
* making a better decision
* protecting of data
And more....
10- What are the disadvantages of a Current ERP System?
* Losses resulting from an unsuccessful implementation
* Requires a huge hardware, software, and services
* converting data from legacy systems to the new integrated system
* It requires more training to reach the required skill
* Higher salaries for employees working on these systems.
11- What is the theory of constraints?
It is a system to improve the thinking of human about problems, also It includes manufacturing operations. This theory is based on that: improving any process is done by improving the slowest part of the process, not by increasing the efficiency.
12- What is the constraint?
The constraint is the slowest part of the production process
13- What are the steps in a TOC analysis?
1) Identify the Constraint
2) Determine the Most Profitable Product Mix Given the Constraint
3) Maximize the Flow through the Constraint
4) Increase Capacity at the Constraint
5) Redesign the Manufacturing Process for Greater Speed and flexibility
14- What are the levels of capacity?
1) Theoretical capacity
2) Practical capacity
3) Normal capacity
15- What is the theoretical capacity?
Theoretical capacity is the optimum level of products that can be completed without wastage or downtime.
16- What is the Practical capacity?
Practical is the highest level of production reasonably achievable considering planned and unplanned downtime (such as set-up, maintenance, downtime, etc..). It also expects waste
17- What is the Normal capacity?
Normal capacity is the average level of production that can be completed through a period of time.
18- What are the requirements for effective capacity cost management requires?
1) Investment Analysis
2) Capacity Assessment
3) Manufacturing Process Assessment
19- What are the steps of Porter’s model of the decision process?
1) Identifying the options that related with their size, type, degree of vertical integration
2) Forecasting demand, input costs, and developments of technology.
3) Analysis of competitors to expect when each of them will expand.
4) Predicting the capacity of total industry and market shares of firms
5) Inconsistencies test.
