Functions of inventory control
To provide maximum supply service, consistent with maximum efficiency & optimum investment.
To provide cushion between forecasted & actual demand for a material
Economic order of quantity
EOQ = Average Monthly Consumption X Lead Time [in months] + Buffer Stock Stock on hand
Re-order level: stock level at which fresh order is placed.
Average consumption per day x lead time + buffer stock
Lead time: Duration time between placing an order & receipt of material
Ideal 2 to 6 weeks.
(ABC = Always Better Control)
This is based on cost criteria.
It helps to exercise selective control when confronted with large number of items it rationalizes the number of orders, number of items & reduce the inventory.
About 10 % of materials consume 70 % of resources
About 20 % of materials consume 20 % of resources
About 70 % of materials consume 10 % of resources

How does JIT differ from MRPII? Briefly discuss the basic requirements and assumptions of JIT implementation.
'Just In Time - JIT'
An inventory strategy companies employ to increase efficiency and decrease waste by receiving goods only as they are needed in the production process, thereby reducing inventory costs.
This method requires that producers are able to accurately forecast demand.
A good example would be a car manufacturer that operates with very low inventory levels, relying on their supply chain to deliver the parts they need to build cars. The parts needed to manufacture the cars do not arrive before nor after they are needed, rather they arrive just as they are needed.
This inventory supply system represents a shift away from the older "just in case" strategy where producers carried large inventories in case higher demand had to be met.
Just in time production (JIT)
Just in time is a pull system of production, so actual orders provide a signal for when a product should be manufactured. Demand-pull enables a firm to produce only what is required, in the correct quantity and at the correct time.
This means that stock levels of raw materials, components, work in progress and finished goods can be kept to a minimum. This requires a carefully planned scheduling and flow of resources through the production process. Modern manufacturing firms use sophisticated production scheduling software to plan production for each period of time, which includes ordering the correct stock. Information is exchanged with suppliers and customers through EDI (Electronic Data Interchange) to help ensure that every detail is correct.
Supplies are delivered right to the production line only when they are needed. For example, a car manufacturing plant might receive exactly the right number and type of tyres for one days production, and the supplier would be expected to deliver them to the correct loading bay on the production line within a very narrow time slot.
Advantages of JIT
Lower stock holding means a reduction in storage space which saves rent and insurance costs
As stock is only obtained when it is needed, less working capital is tied up in stock
There is less likelihood of stock perishing, becoming obsolete or out of date
Avoids the build-up of unsold finished product that can occur with sudden changes in demand
Less time is spent on checking and re-working the product of others as the emphasis is on getting the work right first time
Disadvantages of JIT
There is little room for mistakes as minimal stock is kept for re-working faulty product
Production is very reliant on suppliers and if stock is not delivered on time, the whole production schedule can be delayed
There is no spare finished product available to meet unexpected orders, because all product is made to meet actual orders however, JIT is a very responsive method of production
Manufacturing Resource Planning (MRP II) is defined by APICS as a method for the effective planning of all resources of a manufacturing company. Ideally, it addresses operational planning in units, financial planning in dollars, and has a simulation capability to answer "what-if" questions and extension of closed-loop MRP.
Manufacturing Resource Planning (or MRP2) -
This is not exclusively a software function, but a marriage of people skills, dedication to data base accuracy, and computer resources. It is a total company management concept for using human resources more productively.
MRP II is not a proprietary software system and can thus take many forms. It is almost impossible to visualize an MRP II system that does not use a computer, but an MRP II system can be based on either purchasedlicensed or in-house software.
Almost every MRP II system is modular in construction. Characteristic basic modules in an MRP II system are:
* Master Production Schedule (MPS)
* Item Master Data (Technical Data)
* Bill of materials (BOM) (Technical Data)
* Production Resources Data (Manufacturing Technical Data)
* Inventories and Orders (Inventory Control)
* Purchasing Management
* Material Requirements Planning (MRP)
* Shop Floor Control (SFC)
* Capacity planning or Capacity Requirements Planning (CRP)
* Standard Costing (Cost Control)
* Cost Reporting / Management (Cost Control)
together with auxiliary systems such as:
* Business Planning
* Lot Traceability
* Contract Management
* Tool Management
* Engineering Change Control
* Configuration Management
* Shop Floor Data Collection
* Sales Analysis and Forecasting
* Finite Capacity Scheduling (FCS)
and related systems such as:
* General Ledger
* Accounts Payable (Purchase Ledger)
* Accounts Receivable (Sales Ledger)
* Sales Order Management
* Distribution Requirements Planning (DRP)
* [Automated] Warehouse Management
* Project Management
* Technical Records
* Computer-aided design/Computer-aided manufacturing (CAD/CAM)
The MRP II system integrates these modules together so that they use common data and freely exchange information, in a model of how a manufacturing enterprise should and can operate. The MRP II approach is therefore very different from the point solution approach, where individual systems are deployed to help a company plan, control or manage a specific activity. MRP II is by definition fully integrated or at least fully interfaced.
MRP II systems have been implemented in most manufacturing industries. Some industries need specialised functions e.g. lot traceability in regulated manufacturing such as pharmaceuticals or food. Other industries can afford to disregard facilities required by others e.g. the tableware industry has few starting materials mainly clay and does not need complex materials planning. Capacity planning is the key to success in this as in many industries, and it is in those that MRP II is less appropriate.
Material Requirements Planning (MRP) and Manufacturing Resource Planning (MRPII) are predecessors of Enterprise Resource Planning (ERP), a business information integration system. The development of these manufacturing coordination and integration methods and tools made todays ERP systems possible. Both MRP and MRPII are still widely used, independently and as modules of more comprehensive ERP systems, but the original vision of integrated information systems as we know them today began with the development of MRP and MRPII in manufacturing.
The vision for MRP and MRPII was to centralize and integrate business information in a way that would facilitate decision making for production line managers and increase the efficiency of the production line overall. In order to calculate the raw materials needed to produce products and to schedule the purchase of those materials along with the machine and labor time needed, production managers recognized that they would need to use computer and software technology to manage the information.
Originally, manufacturing operations built custom software programs that ran on mainframes.
Material requirements planning (MRP) was an early iteration of the integrated information systems vision. MRP information systems helped managers determine the quantity and timing of raw materials purchases. Information systems that would assist managers with other parts of the manufacturing process, MRPII, followed. While MRP was primarily concerned with materials, MRPII was concerned with the integration of all aspects of the manufacturing process, including materials, finance and human relations.
MRPII was designed to integrate a lot of information by way of a centralized database. the vision had been established, and shifts in the underlying business processes along with rapid advances in technology led to the more affordable enterprise and application integration systems that big businesses and many medium and smaller businesses use today .
Material requirements planning (MRP) and manufacturing resource planning (MRPII) are both incremental information integration business process strategies that are implemented using hardware and modular software applications linked to a central database that stores and delivers business data and information.
MRP is concerned primarily with manufacturing materials while MRPII is concerned with the coordination of the entire manufacturing production, including materials, finance, and human relations. The goal of MRPII is to provide consistent data to all players in the manufacturing process as the product moves through the production line.
Paper-based information systems and non-integrated computer systems that provide paper or disk outputs result in many information errors, including missing data, redundant data, numerical errors that result from being incorrectly keyed into the system, incorrect calculations based on numerical errors, and bad decisions based on incorrect or old data. In addition, some data is unreliable in non-integrated systems because the same data is categorized differently in the individual databases used by different functional areas.
MRPII systems begin with MRP, material requirements planning. MRP allows for the input of sales forecasts from sales and marketing. These forecasts determine the raw materials demand. MRP and MRPII systems draw on a master production schedule, the breakdown of specific plans for each product on a line. While MRP allows for the coordination of raw materials purchasing, MRPII facilitates the development of a detailed production schedule that accounts for machine and labor capacity, scheduling the production runs according to the arrival of materials. An MRPII output is a final labor and machine schedule. Data about the cost of production, including machine time, labor time and materials used, as well as final production numbers, is provided from the MRPII system to accounting and finance .
For the companies that want to integrate their other departments with their manufacturing management, ERP software are necessary.
MRP II systems can provide:
Better control of inventories
Productive relationships with suppliers
For design / engineering:
Improved design control
Better quality and quality control
For financial and costing:
Reduced working capital for inventory
Improved cash flow through quicker deliveries
Accurate inventory records
JIT is not about automation. JIT eliminates waste by providing the environment to perfect and simplify the processes. JIT is a collection of techniques used to improve operations It can also be a new production system that is used to produce goods or services.
"a philosophy of manufacturing based on planned elimination of all waste and continuous improvement of productivity. It encompasses the successful execution of all manufacturing activities required to produce a final product, from design engineering to delivery and including all stages of conversion from raw material onward. The primary elements include having only the required inventory when needed; to improve quality to zero defects; to reduce lead time by reducing setup times, queue lengths and lot sizes; to incrementally revise the operations themselves; and to accomplish these things at minimum cost."
When the JIT principles are implemented successfully, significant competitive advantages are realized. JIT principles can be applied to all parts of an organization: order taking, purchasing, operations, distribution, sales, accounting, design, etc.
Elimination of Waste:
JIT usually indentifies seven prominent types of waste to be eliminated:
Waste from Overproduction Waste of waiting/idle time
Transportation Waste Inventory Waste
Processing Waste Waste of Motion
Waste from Product Defects
Material related costs are reduced by reducing the number of suppliers a company deals with and developing long-term contracts through CREATIVE SUPPLIER NETWORKING , eliminating the need to count individual parts, reducing order scheduling, eliminating expediting, simplifying receiving systems, eliminating receiving inspection, eliminating most unpacking, eliminating the stocking of inventory, and eliminating excess material spoilage.
Manufacturing related costs are reduced by design for manufacture and design for assembly techniques where unnecessary parts or processes are eliminated. They are also reduced through the elimination of excess material handling, inspections, and storage of parts. The primary goal is to eliminate non-value adding tasks. Quick change over techniques replace long set-up times. Cells will replace traditional assembly lines.
Visual controls are often used to schedule the production of parts in place of systems such as MRP. Statistical process control is used to assure that the outcome of production is consistently met with desired results.
The underlying FACT of JIT manufacturing is very simple. Buy only what is needed to produce finished goods that will be sold in the short term, rather than stockpiling large quantities of goods that may remain in inventory for an extended period of time. The idea is to make use of those raw materials as soon as they are delivered. At the same time, the finished goods should be on the way to consumers shortly after rolling off the ASSEMBLY LINE . In order for JIT to work, this means careful planning and scheduling of both the ordering of raw materials and the labor and equipment needed to successfully deliver the goods on time.
Manufacturing plants often benefit from making use of JIT manufacturing processes. This is particularly true with industries where there is a great deal of variance in demand over the course of a year. Companies operating within industries that go through cycles of demand will project when the next big wave of demand will begin and secure raw materials just in time to begin producing finished goods to meet that demand. As a result, finished products do not have to set in warehouses for months on end. Instead, they may be stored for a very short time before being shipped to the buyer.
