Distribution requirements planning (DRP) is a system for inventory management and distribution planning

Extends the concepts of MRPII

Distribution Requirements PlanningDistribution Requirements Planning


Management uses DRP to plan and coordinate: Transportation Warehousing Workers Equipment Financial flows

Uses of DRPUses of DRP


Electronic Data InterchangeElectronic Data Interchange

EDI – the direct transmission of interorganizational transactions, computer-to-computer, including purchase orders, shipping notices, and debit or credit memos.


Increased productivity Reduction of paperwork Lead time and inventory reduction Facilitation of just-in-time systems Electronic transfer of funds Improved control of operations Reduction in clerical labor Increased accuracy

Electronic Data InterchangeElectronic Data Interchange


Efficient consumer response (ECR) is a supply chain management initiative specific to the food industry Reflects companies’ efforts to achieve quick

response using EDI and bar codes

Efficient Consumer ResponseEfficient Consumer Response


E-Commerce: the use of electronic technology to facilitate business transactions

Applications include Internet buying and selling E-mail Order and shipment tracking Electronic data interchange

E-CommerceE-Commerce


Companies can: Have a global presence Improve competitiveness and quality Analyze customer interests Collect detailed information Shorten supply chain response times Realize substantial cost savings Create virtual companies Level the playing field for small companies

Advantages E-CommerceAdvantages E-Commerce

Collaborative Planning, Forecasting, and Replenishment

Focuses on information sharing among trading partners

Forecasts can be frozen and then converted into a shipping plan

Eliminates typical order processing

Supply Chain Performance DriversSupply Chain Performance Drivers

1. Quality

2. Cost

3. Flexibility

4. Velocity

5. Customer service


VelocityVelocity

Inventory velocity

The rate at which inventory(material) goes through the supply chain

Information velocity

The rate at which information is communicated in a supply chain


Barriers to integration of organizations

Getting top management on board

Dealing with trade-offs

Small businesses

Variability and uncertainty

Long lead times

ChallengesChallenges


1. Lot-size-inventory Bullwhip effect

2. Inventory-transportation costs Cross-docking

3. Lead time-transportation costs

4. Product variety-inventory Delayed differentiation

5. Cost-customer service Disintermediation

Trade-offsTrade-offs



Bullwhip effect

Inventories are progressively larger moving backward through the supply chain

Cross-docking

Goods arriving at a warehouse from a supplier are unloaded from the supplier’s truck and loaded onto outbound trucks

Avoids warehouse storage



Delayed differentiation

Production of standard components and subassemblies, which are held until late in the process to add differentiating features

Disintermediation

Reducing one or more steps in a supply chain by cutting out one or more intermediaries
