When deciding on the location of a facility there are a large number of factors that must be considered:. To name a few. One major consideration is operating costs and a significant contribution to operating costs is transportation costs. All transportation costs have fixed and variable components. The variable components change as a result of distance traveled.

This example uses the Center or Gravity Method to determine the most appropriate position for a regional distribution center that delivers material to local hubs in 6 cities.

The local hubs have been located close to population centers. A look at the map shows that to be in Reading PA. The large volumes from NY, Philadelphia, and Baltimore has driven the location towards the southern portion of our region.

It is possible for this method to locate a facility in a place that is not feasible such as in a body of water or on a mountain. In those cases, your judgment has to be used to make adjustments or an alternate method of placement can be used. When deciding on the location of a facility there are a large number of factors that must be considered: Access to transportation Access to a labor pool Power and Communications Labor Rates Capital Costs Taxes To name a few.

Using the Method: Locate the delivery locations on a map and look up the expected shipping volume to each location. The shipping volume can be of units of your choice. If the loads vary in size you may want to use total weight shipped or the sum of units x weight over all shipments. In our example, we are using shipment count. Using a grid assign an X and Y coordinate to each location. Search Search for:.Location Strategy in Operations Management is an important factor to be considered.

It is important because it helps in determining the place of manufacture. The place of manufacture needs to have certain qualities of features where the manufacturing process takes place hassle-free. Center of Gravity is one such method or strategy which can determine the effectiveness of a location. Firms throughout the world are using the concepts and techniques in Operations Management to address the location decision because location greatly affects both fixed and variable costs.

Location has a major impact on the overall risk and profit of the company. Other costs that may be influenced by location include taxes, wages, raw material costs, and rents. Companies may also relocate their manufacturing or service facilities because of shifts in demographics and customer demand.

The location decision often depends on the type of business. For industrial location decisions, the strategy is usually minimizing costs, although innovation and creativity may also be critical. For retail and professional service organizations, the strategy focuses on maximizing revenue. Warehouse location strategy, however, may be driven by a combination of cost and speed of delivery. The objective of the location strategy is to maximize the benefit of the location to the firm.

Key multinationals in every major industry, from automobiles to mobile phones, now have or are planning a presence in each of their major markets. Location decisions to support a low-cost strategy require particularly careful considerations.

Center of Gravity Technique for Locating a Distribution Center

Once management is committed to a specific location, many costs are firmly in place and difficult to reduce. For instance, if a new factory location is in a region with high energy costs, even good management with an outstanding energy strategy is starting at a disadvantage. Management is in a similar bind with its human resource strategy if the labor in the selected location is expensive, ill-trained or has a poor work ethic.

Consequently, hard work to determine an optimal facility location is a good investment. When creativity, innovation and research and development investments are critical to the operations strategy, the location criteria may change from a focus on costs.

When innovation is the focus, four attributes seem to affect overall competitiveness as well as innovation. The Center of Gravity Method is a mathematical technique used for finding the location of a distribution centre that will minimize distribution costs. The method takes into account the location of markets, the volume of goods shipped to those markets and shipping costs in finding the best location for a distribution center. The first step in the centre of gravity method is to place the locations on a coordinate system.

The origin of the coordinate system and the scale used is arbitrary, just as long as the relative distances are correctly represented. This can be done easily by placing a grid over an ordinary map. The centre of Gravity is determined using equations. Since the number of containers shipped each month affects costs, distance alone should not be the principal criterion. The centre of gravity method assumes that cost is directly proportional to both distance and volume shipped.

The ideal location is that which minimizes the weighted distance between the warehouse and its retail outlets, where the distance is weighted by the number of containers shipped.

The center of gravity method aims at minimizing the total shipping cost, i. If the shipping quantities for all destination points are equal, the location at which the transportation cost will be minimum can be identified by taking the arithmetic averages of the X and Y coordinates of the destination. But if the shipping quantities are unequal, the location can be found using a weighted average approach the quantities to be shipped are taken as weights. The center of gravity of a geographical location can be identified by calculating the X and Y coordinate values of the location that would minimize transportation costs.

The coordinates of the center of gravity can be identified by. Figure shows the X and Y coordinates of seven retail locations of a retail chain. Information regarding the quantity to be shipped to each of the seven locations is given in Table 1. Using the center of gravity method, identify the coordinates of the optimal location for the warehouse.

The X and Y coordinates of the point of center of gravity are 8. Figure 6. Email based Operations Management assignment help - homework help at Expertsmind.

Or another hot area to consider in build-to-order fulfillment is the explosion of 3D Printing Companies. There are at least 3 critical items that allow you to reduce costs and increase service level in warehousing:. Where to build a distribution center, fulfillment center, or warehouse is a strategic question.

Where to build your next warehouse is an incredibly important question to answer. The above are important criteria and should be considered. One common approach to identifying where to build the next single fulfillment center location is a method called the Center of Gravity Method. The Center of Gravity Method is an approach that seeks to compute geographic coordinates for a potential single new facility that will minimize costs. We calculate the X and Y coordinates using these equations where Cx is the X horizontal axis coordinate for the new facility.

Cy is the Y vertical axis coordinate for the new facility, dix is the X coordinate of the existing location, diy is the Y coordinate of the existing location, and Vi is the volume of goods moved to or from the ith location. As I mention earlier, there are other factors to consider. What this method allows is a point of departure — or, literally, a starting point of where from the perspective of longitude and latitude you options are for where to grow your fulfillment or logistics network.

Given the following assumptions below, what are the coordinates for the new potential location? Once a coordinate or several are identified given the current logistics network context, then other factors must be considered. This is just the beginning — a point of departure.

Article Edit. Learn why people trust wikiHow.Plant and distribution center location is a common problem faced by logistics managers. Increased production economics of scale and reduced transportation cost have focused attention on distribution centers. In recent years, location analysis has been further extended to include logistics channel design as a result of global sourcing and marketing decisions.

Global operations increase logistics channel decision complexity, design alternatives and related logistics cost. Typical management questions Location analysis problems are very complex and data intense. Complexities are created because of the number of locations multiplied by the alternative location sites multiplied by the stocking strategies for each location.

Data intensity is created because the analysis requires detailed demand and transportation information. The techniques used are:. Analytic techniques: generally describe methods that identify the center of gravity of logistics geography. A center of gravity method is appropriate for locating a single distribution plant or center. A number of methods both mathematical and non mathematical can be applied to a problem of a single location.

The cost and complexity of the technique is to be matched to the difficulty of the problem. In the following example technique employed is evolved from analytic geometry. The model is based on Cartesian co-ordinates, where the horizontal axis is labeled as the x-axis, and the vertical axis is labeled as the y-axis. Taken together, these co-ordinates define unique points. The x and y co-ordinate system can be used to calculate the distance between any two points on the plane using the Pythagoras theorem.

By use of this basic system of orientation, it is possible to replicate the geographic market area in which the distribution center is to be located. This method to solve the location problem determines the ideal co-ordinate position of the distribution warehouse on the basis of distance, weight or a combination of both.

The computation is a weighted average of the distance, weight or combined factors, with the warehouse location as the dependent variable. The algebraic solution may use either the weighted average x and y co-ordinate or the median location. The median location uses the coordinate location with half the demand on each side.

The formula of this calculation depend on the independent variables expressed in the location measure. The problem is in a manner such that identical service standards exist for all potential distribution warehouse locations.

The objectives are to minimize transportation cost. Transportation cost are a function of time, weight and distance.

Historically, in mathematical techniques it is not possible to consider all the factors together. The 4 solution methods that consider combination of factors are:. Your email address will not be published. This site uses Akismet to reduce spam.
