Challenges specific to that environment include very short product life cycles, and store policies whereby an article is removed from display whenever one of its key sizes stocks out. To solve this problem, we first formulate and analyze a stochastic model predicting the sales of an article in a single store during a replenishment period as a function of demand forecasts, the inventory of each size initially available, and the store inventory management policy just stated. We then formulate a mixed-integer program embedding a piecewise-linear approximation of the first model applied to every store in the network, allowing us to compute store shipment quantities maximizing overall predicted sales, subject to inventory availability and other constraints. We report the implementation of this optimization model by Zara to support its inventory distribution process, and the ensuing controlled pilot experiment performed to assess the model's impact relative to the prior procedure used to determine weekly shipment quantities.
Operations management is in regard to all operations within the organization responsible for creating goods and services that organizations pass to their customers.
This function is at the heart of all organizations, giving the means of achieving their aims and reason for their existence. A great deal of focus in operations is on efficiency and effectiveness of such a process.
An example of successful operations strategy in the retail industry is the strategy employed by Zara which is discussed in this critique. Zara started as a single shop in La Coruna and then rapidly spread its wings to 68 countries; opening a store each day - one of the fastest global expansions the world has ever seen.
This elements feature in every aspect of the business. Founded in ; this super- heated performers in soft retail fashion market in recent years; is engaged in textile design, manufacturing and distribution.
The group operates approximately stores. What makes Zara such successful when other competitors are falling? Which business model does Zara use?
What are the challenges that Zara faces? The questions can be best answered through a SWOT analysis of the firm. An efficient supply chain is becoming more and more key success factor for companies. Zara as part of the Inditex group has a very strong distribution network.
Hence their superior supply chain management enables the retailer to deliver goods within 24 hours of the receipt of order at its European stores and 40 hours at its American and Asian outlets. Just In Time concept is a concept from Japanese philosophy focusing on the elimination of waste in management or production system.
Zara designs all its products itself. Concurrent method design could be an adjective to the of product design process which involve the whole commercial teamdesigners, market specialist, procurement team as well as continuous feedback from store managers to ensure that the products reach the customer just in time.
Designs inspiration is copied from different sources trade fairs, catwalks, magazines from all around the world. It is worth to mention that out of 40, designs only 10, are approved. This illustrates the flexibility of ideas generation and on the other hand the huge number of designs reflects the ability to meet almost all the fashion requirements by customers of all ages up to Zara business is organized around processes not functions, to close the information loop.
All team is involved in all processes. This method minimizes the time as decision is conducted in one room, and in direct proximity to the information. As a result, Zara reduces the inherent uncertainty associated with new designs in this industry that is characterized by long lead times and very high variability of demand e.
By owning its in-house production Zara is able to be flexible in the amount, frequency, and variety of new styled products.
Zara has outsourced less manufacturing than its peers. It has 22 factories and runs many of them often only in one shift leaving extra capacity to respond quickly to seasonality and unforeseen demand.
Zara is outsourcing all the labour intensive tasks mainly the sewing, while the cutting is done in-house. Zara applies technology in areas that speed up complex tasks, lower cycle time and reduce error. It is technology that helps Zara identify and manufucture the clothes that customers want, get those products to the market quickly Zara stores managers carry handheld Casio computers to send online information to headquarters like selling trends, customers comments, or placing orders.
Designers send their design suggestions to factory and to distribution department by scanning a design into a computer and electronically transmit to factory computers including computers controlled cutting equipment.
Designers input the designs patterns into CAD systems which automatically feed into the cutting machines in the factories ensuring the required quality of outputs and having a minimum fabrics waste.
Zara seems fully aware of the adage: Inventory optimization models are in place to help the the firm determine how many of which items in which sizes should be delivered to stores during the twice aweek shipment ensuring sores stock just what they want.
Zara designs around 10, new models every year and replenishes ranges within every one of its retail stores twice per week, but in strictly limited quantities of stock.
But it also avoids build-up of large quantities of unpopular stock. There are two orders per week from each store on specific days and hours, with shipments in La Coruna usually prepared overnight.
Trucks leave at specific times and shipments arrive in stores at specific times. Garmentsare pre-hung, already labeled and priced.
This large and high-tech facility also has extra capacity on hand to enable Zara to react to weekly and monthly demand fluctuations. For example, it operates typically 4. It is interesting to know that Zara can get the product from the idea to the store in15 days time, where the industry standard is 6 months, the design and production process is very efficient and harmonized due to the use of the different methods that suites their line of business and set new model to look for.
