After reading some rather good comments on what JIT and MRP is and how we have defined these two systems in class.I would like to take this discussion in a new direction.
I agree with sir's comments on what these two systems are and how we have defined them and I’m sure we will all agree that we have learned something new on this topic than any other topic within the “Internet” - but amongst the rather fantastical words used to define these two systems I feel we have “dressed” what JIT and MRP is and particularly whether it actually works within today’s production and business world??
My feelings are that JIT in particular doesn’t work in majority of companies today.
There appear to be to many risks involved within this system and I believe that there isn’t the room for errors to be made. JIT can save a company time, money and waste but it doesn’t tackle the fundamentals of the physical logistical side, i.e, delivery mistakes or lateness of a product or component. If a product or service isn’t delivered and has detrimental effects to a customer who buys your product/service on the high street they will simply go elsewhere (to a competitor) and buy the same product from them. Customers aren’t patient today as there is so much choice to buy the same product elsewhere.
Too many elements have to be 100% correct, i.e flexible workforce, good suppliers, quality, speed and dependability for the JIT system too work and if one element goes wrong then your company will suffer with great effects – loss in profit due to lower sales, bad reputation as you can’t deliver products etc.
Upon this, I would say that JIT is risky in a competitive market, which incidentally is the case with nearly all products on the market today. JIT was a revolutionary concept maybe 20 years ago and up until this date but I feel that it could cause more harm than good due to the amount of competition today, The only exception to this is in a niche market where customers don’t have the same choice to buy elsewhere as they do in a competitive market and JIT will work.
Please feel free to comment on my views.

WHAT IS SLACK WITH RESPECT TO SETUP??
a)Take the minmum delay values along the data path and maximum delay values along the clock path.
b)ARRIVAL TIME is always calculated along the data path.
c) ARRIVAL TIME =Propogation delay of the flip flop+propogation delay of the combinational logic+latency.
d)REQUIRED TIME is always calculated along the clock path.
e)REQUIRED TIME=Clock period + skew(differnce in arrival of clock b/w two flip flop)+latency+hold time of the flip flop.
SLACK(setup) = ARRIVAL TIME-REQUIRED TIME
b)ARRIVAL TIME is always calculated along the data path.

SOME IMPORTANT TERMS
Data Collection Terminals
Fixed and mobile computing devices that aquire data by reading bar codes, magnetic stripes, RFID tags, etc. and transmit that data to enterprise systems (i.e. ERP, WMS, TMS) for the purpose of providing real-time track and trace visibility. Enterprise Resource Planning (ERP)
Enterprise Resource Planning goes beyond material requirements planning (MRP I) and Manufacturing Resource Planning (MRP II) to encompass all functions within an enterprise as well as its trading partners.
Forecasting & Replenishment
Forecasting seeks to predict levels of weekly or monthly product activity over a time horizon. Replenishment, within a warehouse, is the process of moving inventory from secondary storage areas into fixed storage locations. Within a supply chain or a multiplant environment, it is the process of moving inventory between facilities to meet demand. Inventory Management
Handles all functions related to the tracking and management of material. This would include the monitoring of material moved into and out of stockroom locations and the reconciling of the inventory balances. Also may include ABC analysis, lot tracking, cycle counting support, etc.
Labor Management — Workforce
Raise fulfillment proficiency to the highest level by monitoring all direct and indirect labor, and providing feedback to workers and supervisors as activities are completed. Manufacturing Execution Systems (MES)
A shop floor control system which includes either manual or automatic labor and production reporting as well as online inquiries and links to tasks that take place on the production floor. MES includes links to work orders, receipt of goods, shipping, quality control, maintenance, scheduling, and other related tasks.
Mobile Devices
A portable device that uses wireless technologies to transmit and exchange data. Along with mobile computing devices such as laptops and smart phones, PDAs represent the new frontier of computing as desktop computers find less and less favor among every day users. Material Requirements Planning (MRP)
A software application that uses bill of material, routing, inventory, work order, sales order, purchase order, transfer order, and other information to calculate requirements for materials.
Order Fulfillment
In the company's Inventory Management Cycle, this is the vendor's business process. The vendor receives the purchase order from the company, picks and packs the merchandise, and sends it to the retailer. Picking Solutions
Information technology enabled solutions that increase efficiency and effectiveness of pick, pack, and put-away operations within warehousing and manufacturing facilities. Solutions that support wave picking, pick-to-light, and voice picking are featured in this section.
Printers
Generic term applied to data-processing devices that produce full-size hard copy from computers. Among impact printers: serial printers, line printers, chain printers, bar printers, wheel printers and matrix printers. Non-impact printers, like ink jet printers, are based on printing principles similar to those employed in cathode ray tubes. Product Lifecycle Management
IT-enabled systems that facilitate intra- and inter-enterprise collaboration and communication throughout a product's entire lifecycle, from initial R&D, through engineering design, through manufacturing release, through production ramp up, through field service, to end-of-life.
Real-Time Production
Real-time production uses computers designed to receive, process, and respond to data within a time frame set by outside events, e.g., for air traffic control. In many real-time systems, severe consequences result if the timing and logical correctness of the system are not satisfied. Real-time process monitoring and control. Repetitive Manufacturing
The production of discrete units in a high-volume concentration of available capacity using fixed routings. Products may be standard or made from standard modules. Production management is usually based on the production rate.
RFID
RFID stands for radio frequency identification. It is an automatic identification technology whereby digital data encoded in an RFID tag or "smart label" is captured by a reader using radio waves. Shopfloor Management
Enable comprehensive, real-time management of shop floor activities, including complex lot transactions, dynamic routing, end-to-end genealogy of products, and modeling and tracking of operation yield costs.
Supply Chain Execution
Optimizes customer response by merging two important functions: the storage and delivery of finished goods. Execution may involve final assembly and packaging of products within the warehouse environment. Supply Chain Management
The use of information technology to endow automated intelligence to an ever-growing network of delivery vehicles, distribution centers, factories, and raw material suppliers. That way, each player in the supply chain to conduct business with the latest and best information from everyone else in the chain.
Supply Chain Services
Combinations of global warehousing and logistics, finance, information technology, and asset management, external industry-wide data, and supply chain services that allow customers to increase their overall business knowledge, helping them to make better decisions. Transportation Management Systems (TMS)

TOP STORIES !
As per the latest news companies are adopting BI in their industriesBusiness Intelligence in the Supply Chain? It is now!
Business Intelligence (BI) services are not just for the top executives anymore. A new report suggests supply chain managers have sensed BI can help their day-to-day operations, too. Traditionally, the concept of using software for Business Intelligence (BI) has been the domain of top executives crunching numbers to analyze business performance or predict the course of the company's future. No one ever thought of using BI to manage the day-to-day operations of the supply chain.
Not until now, that is. "Supply Chain Intelligence: Adopt Role-Based Operational Business Intelligence and Improve Visibility," is challenging that tradition. Supply chain managers, procurement, and management professionals have gotten wind of the benefits of BI, and they want to use the new tools.

The Toyota Prius has landed on Indian shores waving the eco-friendly flag. It may be the first word in hybrid cars internationally, but does it really have a place in the Indian automotive scenario? Lets See...
Supply chain Management:
Supply chain is a network that includes vendors of raw materials,plants that transform those materials into useful products,and distribution centers to get those products to customers.
Without anu specific efforts to coordinate the overall supply chain system, each organization in the network has its own agenda and operates independently from the others.HOwever, such an unmanaged network results in inefficiencies. Clearly there is mch to be gained by managing the supply chain network to improve its performance and efficiency.
