FTC is a common technique to analyze the layout of the facility and transfer station workpiece. This method shows us how often inter-facility transfer of work activity, so the analysis is performed based on the frequency of the material must be removed to the distance that must be taken.The steps to analyze the flow of material to use From To Chart:1. Get the flow of inter-facility transfer of the workpiece2. Make the FTC based on the displacement of the workpiece3. Obtain distance data movement of the workpiece.From the results of this analysis will be obtained within the workpiece transfer between machines. Calculations can be done by knowing the data transport capacity and demand to determine the amount of displacement can be done using the method of measuring the distance of transport in accordance with the conditions of the production floor.
Distance MovementDisplacement distance we can use to analyze the layout. The smaller the distance of displacement that occurs, the better layout in terms of distance. However, the distance can not be directly used because it is still worth noting the technical side. Meanwhile, to get the minimum of the total distance moved there baberapa things to note are:a. Displacement of the workpiece that has cultivated a large frequency minimum distanceb. Arranged back-flow does not occur.
Types of Measurement Distance TransportDistance measurement is required in determining whether the results of the design layout has better results. Determination of the distance measure can be calculated by several methods of measurement. Meteode-method is determined by how easily the operator using the equipment, the time required to collect the material and the types of transportation used. The types of distance measurement methods are:A. EucledianThis measurement method is based on the measurement of straight-line distance between the center of the facility which is a center of gravity of each facility. This species is quite useful and easy to understand, while the equation for distance using eucledian method is:
.................................
Where xi: x coordinate of the center of the facility ixj: x coordinate of the center facilities jyi: y coordinate of the center of facility i
yj: y coordinate of the center facilities j
dij: the distance between the centers facility i and j
Methods eucledian2. Squared EucledianMeasurements performed on squared euledian also based on a straight-line distance between the center of the facility, (in the picture above), but the weight of a given displacement is greater than euledian methods, but the method is little used in the measurement of enterprise applications. Equations to obtain the distance by using the method used the equation:
................................. 2. 23. RectilinierThis type of measurement is often known as Manhattan, right-angle or rectangular metric. Rectilinier distance measurement most commonly used because it is easy to calculate, and suitable for a wide range of issues. Shooting distance can be seen in the picture above, while the displacement equations are:
.................................
4. Distance aisleDistance calculation using this method is based on the actual distance traversed by the existing transportation routes. Distance calculation here is based on sum of the path.5. Shortest PathThis type of distance measurement used to determine the distance between two points and the shortest distance to consider. Criteria for the design of the cell can be used to determine the optimal cell configuration. But it must choose the form of several alternative cell design, while the criterion is to minimize the cost of material handling and intracellular intersel. Factors that affect cost are:a. The layout of machines in one groupb. The layout of the machine groupsc. The sequence of the workpiece through the machine and the machine
Systematic Layout Planning (SLP)Richard Muther (1973) has succeeded in creating a concept layout planning using a systematic and organized approach known as the Systematic Layout Planning (SLP). SLP widely applied to various kinds of problems which include problems of production, transportation, warehousing, supporting services, and activities - activities that occur in the office (office).In summary SLP implementation of this procedure can be described in the following diagram:

Systematic Layout Planning (SLP)Richard Muther (1973) has succeeded in creating a concept layout planning using a systematic and organized approach known as the Systematic Layout Planning (SLP). SLP widely applied to various kinds of problems which include problems of production, transportation, warehousing, supporting services, and activities - activities that occur in the office (office).In summary SLP implementation of this procedure can be described in the following diagram:
Procedure in the Systematic Layout PlanningSystematic implementation procedures Layout Planning (SLP) consists of three phases, namely the phase of analysis, synthesis phase (Design Process) and the phase of the selection of alternatives, which will be outlined as follows:
Phase AnalysisAt this phase, the initial step is the collection of data to be used for layout planning based on ongoing activities. Data collected include the facility of data and data-related activities of the facility.Further to identify the flow of material relating to the analysis of quantitative measurements for each movement activities - operational activity and identification of operational activities relating to the factors - factors that affect the qualitative operational activity or the location where the facility will be placed.Then from the identification of existing operational activity, can be analyzed the relationship between the activity that occurs with the facility to create a table activity relationship (Activity Relationship Chart / ARC) which is used for layout analysis based on the considerations - qualitative considerations. ARC contains an assessment of the degree of proximity (closeness) between the department or facility of the department or other facilities which tend to be qualitative. Examples of ARC can be seen as follows:
Figure 2.8 Example of Activity Relationship ChartIn the picture above, the letter contained in the ARC describes how the activity of each - each department has a relationship directly or closely related. While the figures contained in the ARC suggests a reason - the reason the determination of the degree of relationship between each - each department. Letter code that describes the degree of relationship between each - each department in particular have been standardized, namely:A = Absolutely NecessaryE = Especially ImportantI = ImportantO = OrdinaryU = UnimportantX = UndesirableAs for the reason - the reason the selection of the degree of this relationship (supplied with code numbers) can be taken based on the characteristics of each activity - each department.The next step is the delineation of the ARC into a diagram, called the Relationship Diagram. On this diagram the degree of relationship between departments or facilities described with different line types for each level are:A = is described by 4 linesE = is described by 3 linesI = 2 lines described byO = 1 line is described byU = no line drawnX = is described by an irregular lineRelationship Diagram in any activity described in a circular or rectangular shape the same, which is then connected to a line that has a sense of the desired degree of relationship as described above. Examples of Relationship Diagrams can be viewed as follows:
Figure 2.9 Relationship Diagram Example
Having completed the activity relationship diagram is analyzed and made, then the next step in this activity is to evaluate the SLP needs derta area land area available for the regulation of all existing facilities.
Phase SynthesisAfter the phase of the analysis carried out an analysis of material flow. The degree of activity relationships of each department / facility and calculate the area and determine the requirements for each area - each facility, then the synthesis phase can be quickly made alternative design layout.Alternative designs can be created by combining the initial consideration - consideration of the needs of the area required by the relationship diagram, it is done with the description of space relationship diagram by first analyzing the extent required and attention to relationship diagram. Depiction of space relationship diagram similar to diagram depiction of relationship, it's just the shape - rectangular shape that had the same changed in accordance with the requirements of the department kuasan area / facility in question.Based on the space relationship diagram which has been established, the next step is to design a layout that might be an alternative to make modifications as necessary based on the limitations - limitations and practical considerations - other special considerations. This layout design can generally be expressed in a blokplan which is a block diagram presenting a certain scale of a building. Then based on this blokplan, detail layout can be designed to fit and can usually be more than one design layout.
Phase Selection of AlternativesIn this phase of elections on the alternative - an alternative design that was created in the previous phase and an evaluation of the results of the draft if the draft is not to be realized or not by considering all the advantages and drawbacks.
