Make Location-Allocation Layer Tool

Make Location-Allocation Layer

Makes a location-allocation network analysis layer and sets its analysis properties. A location-allocation analysis layer is useful for choosing a given number of facilities from a set of potential locations such that a demand will be allocated to facilities in an optimal and efficient manner.

1.    Input Analysis Network شبكة التحليل المدخلة

The network dataset on which the location-allocation analysis will be performed.

مجموعة بيانات الشبكة التي سيتم إجراء تحليل تخصيص الموقع عليها.

Output Layer Name

Name of the location-allocation network analysis layer to create.

Impedance Attribute

The cost attribute to be used as impedance in the analysis.

Travel From (optional)

Specifies the direction of travel between facilities and demand points when calculating the network costs.

Using this option can affect the allocation of the demand points to the facilities on a network with one-way restrictions and different impedances based on direction of travel. For instance, a facility may be a 15-minute drive from the demand point to the facility, but only a 10-minute trip when traveling from the facility to the demand point.

Location-Allocation Problem Type (optional)

The problem type that will be solved. The choice of the problem type depends on the kind of facility being located. Different kinds of facilities have different priorities and constraints.

Number of Facilities to Find (optional)

Specifies the number of facilities that the solver should locate.

The facilities with a FacilityType value of Required are always part of the solution when there are more facilities to find than required facilities; any excess facilities to choose are picked from candidate facilities.

Any facilities that have a FacilityType value of Chosen before solving are treated as candidate facilities at solve time.

The parameter value is not considered for the Minimize facilities problem type since the solver determines the minimum number of facilities to locate to maximize coverage.

The parameter value is overridden for the Target market share problem type because the solver searches for the minimum number of facilities required to capture the specified market share.

Impedance Cutoff (optional)

Impedance Cutoff specifies the maximum impedance at which a demand point can be allocated to a facility. The maximum impedance is measured by the least-cost path along the network. If a demand point is outside the cutoff, it is left unallocated. This property might be used to model the maximum distance that people are willing to travel to visit your stores or the maximum time that is permitted for a fire department to reach anyone in the community.

Demand points have a Cutoff_[Impedance] property, which, if set, overrides the Impedance Cutoff property of the analysis layer. You might find that people in rural areas are willing to travel up to 10 miles to reach a facility, while urbanites are only willing to travel up to 2 miles. You can model this behavior by setting the impedance cutoff value of the analysis layer to 10 and setting the Cutoff_Miles value of the demand points in urban areas to 2.

Impedance Transformation (optional)

This sets the equation for transforming the network cost between facilities and demand points. This property, coupled with the Impedance Parameter, specifies how severely the network impedance between facilities and demand points influences the solver's choice of facilities.

Demand points have an ImpedanceTransformation property, which, if set, overrides the Impedance Transformation property of the analysis layer. You might determine the impedance transformation should be different for urban and rural residents. You can model this by setting the impedance transformation for the analysis layer to match that of rural residents and setting the impedance transformation for the demand points in urban areas to match that of urbanites.

Impedance Parameter (optional)

Provides a parameter value to the equations specified in the Impedance transformation parameter. The parameter value is ignored when the impedance transformation is of type Linear. For Power and Exponential impedance transformations, the value should be nonzero.

Demand points have an ImpedanceParameter property, which, if set, overrides the Impedance Parameter property of the analysis layer. You might determine that the impedance parameter should be different for urban and rural residents. You can model this by setting the impedance transformation for the analysis layer to match that of rural residents and setting the impedance transformation for the demand points in urban areas to match that of urbanites.

Target Market Share (optional)

Specifies the target market share in percentage to solve for when the Location-Allocation Problem Type parameter is set to Target market share. It is the percentage of the total demand weight that you want your solution facilities to capture. The solver chooses the minimum number of facilities required to capture the target market share specified by this numeric value.

Default Capacity (optional)

Specifies the default capacity of facilities when the Location-Allocation Problem Type parameter is set to Maximize capacitated coverage. This parameter is ignored for all other problem types.

Facilities have a Capacity property, which, if set to a nonnull value, overrides the Default Capacity parameter for that facility.

Start Time (optional)

Indicates the time and date of departure. The departure time can be from facilities or demand points, depending on whether travel is from demand to facility or facility to demand.

If you have chosen a traffic-based impedance attribute, the solution will be generated given dynamic traffic conditions at the time of day specified here. A date and time can be specified as 5/14/2012 10:30 AM.

Instead of using a particular date, a day of the week can be specified using the following dates:

For example, to specify that travel should begin at 5:00 p.m. on Tuesday, specify the parameter value as 1/2/1900 5:00 PM.

Accumulators (optional)

A list of cost attributes to be accumulated during analysis. These accumulation attributes are purely for reference; the solver only uses the cost attribute specified by the Impedance Attribute parameter to calculate the route.

For each cost attribute that is accumulated, a Total_[Impedance] property is added to the routes that are output by the solver.

Use Hierarchy in Analysis (optional)

The parameter is disabled if a hierarchy attribute is not defined on the network dataset used to perform the analysis.

Output Path Shape (optional)

U-Turn Policy (optional)

The U-Turn policy at junctions. Allowing U-turns implies the solver can turn around at a junction and double back on the same street. Given that junctions represent street intersections and dead ends, different vehicles may be able to turn around at some junctions but not at others—it depends on whether the junction represents an intersection or dead end. To accommodate this, the U-turn policy parameter is implicitly specified by how many edges connect to the junction, which is known as junction valency. The acceptable values for this parameter are listed below; each is followed by a description of its meaning in terms of junction valency.

If you need a more precisely defined U-turn policy, consider adding a global turn delay evaluator to a network cost attribute, or adjusting its settings if one exists, and pay particular attention to the configuration of reverse turns. Also, look at setting the CurbApproach property of your network locations.

Restrictions (optional)

A list of restriction attributes to apply during the analysis.

Given that junctions represent street intersections and dead ends, different vehicles may be able to turn around at some junctions but not at others—it depends on whether the junction represents an intersection or dead end. To accommodate this, the U-turn policy parameter is implicitly specified by how many edges connect to the junction, which is known as junction valency. The acceptable values for this parameter are listed below; each is followed by a description of its meaning in terms of junction valency.

If you need a more precisely defined U-turn policy, consider adding a global turn delay evaluator to a network cost attribute, or adjusting its settings if one exists, and pay particular attention to the configuration of reverse turns. Also, look at setting the CurbApproach property of your network locations.

Restrictions (optional)

6.    Number of Facilities to Find (optional) عدد المرافق للبحث (اختياري)

Specifies the number of facilities that the solver should locate.

يحدد عدد التسهيلات التي يجب على المحلل تحديد موقعها.

دائمًا ما تكون المرافق التي تحتوي على قيمة "نوع" التسهيلات "مطلوبة جزءًا من الحل عندما يكون هناك المزيد من التسهيلات التي يمكن العثور عليها أكثر من المرافق المطلوبة ؛ يتم اختيار أي مرافق فائضة للاختيار من المرافق المرشحة.

يتم التعامل مع أي منشآت تحتوي على قيمة "نوع" التسهيلات "المختارة" قبل الحل على أنها منشآت مرشحة في وقت الحل.

لا يتم أخذ قيمة المعلمة في الاعتبار لنوع مشكلة تصغير المرافق نظرًا لأن المحلل يحدد الحد الأدنى لعدد المرافق لتحديد موقعها لزيادة التغطية إلى الحد الأقصى.

تم تجاوز قيمة المعلمة لنوع مشكلة حصة السوق المستهدفة لأن المحلل يبحث عن الحد الأدنى لعدد التسهيلات المطلوبة لالتقاط حصة السوق المحددة.

Impedance Cutoff (optional)

Impedance Cutoff specifies the maximum impedance at which a demand point can be allocated to a facility. The maximum impedance is measured by the least-cost path along the network. If a demand point is outside the cutoff, it is left unallocated. This property might be used to model the maximum distance that people are willing to travel to visit your stores or the maximum time that is permitted for a fire department to reach anyone in the community.

Demand points have a Cutoff_[Impedance] property, which, if set, overrides the Impedance Cutoff property of the analysis layer. You might find that people in rural areas are willing to travel up to 10 miles to reach a facility, while urbanites are only willing to travel up to 2 miles. You can model this behavior by setting the impedance cutoff value of the analysis layer to 10 and setting the Cutoff_Miles value of the demand points in urban areas to 2.

Impedance Transformation (optional)

This sets the equation for transforming the network cost between facilities and demand points. This property, coupled with the Impedance Parameter, specifies how severely the network impedance between facilities and demand points influences the solver's choice of facilities.

Demand points have an ImpedanceTransformation property, which, if set, overrides the Impedance Transformation property of the analysis layer. You might determine the impedance transformation should be different for urban and rural residents. You can model this by setting the impedance transformation for the analysis layer to match that of rural residents and setting the impedance transformation for the demand points in urban areas to match that of urbanites.

Impedance Parameter (optional)

Provides a parameter value to the equations specified in the Impedance transformation parameter. The parameter value is ignored when the impedance transformation is of type Linear. For Power and Exponential impedance transformations, the value should be nonzero.

Demand points have an ImpedanceParameter property, which, if set, overrides the Impedance Parameter property of the analysis layer. You might determine that the impedance parameter should be different for urban and rural residents. You can model this by setting the impedance transformation for the analysis layer to match that of rural residents and setting the impedance transformation for the demand points in urban areas to match that of urbanites.

Target Market Share (optional)

Specifies the target market share in percentage to solve for when the Location-Allocation Problem Type parameter is set to Target market share. It is the percentage of the total demand weight that you want your solution facilities to capture. The solver chooses the minimum number of facilities required to capture the target market share specified by this numeric value.

Default Capacity (optional)

Specifies the default capacity of facilities when the Location-Allocation Problem Type parameter is set to Maximize capacitated coverage. This parameter is ignored for all other problem types.

Facilities have a Capacity property, which, if set to a nonnull value, overrides the Default Capacity parameter for that facility.

Start Time (optional)

Indicates the time and date of departure. The departure time can be from facilities or demand points, depending on whether travel is from demand to facility or facility to demand.

If you have chosen a traffic-based impedance attribute, the solution will be generated given dynamic traffic conditions at the time of day specified here. A date and time can be specified as 5/14/2012 10:30 AM.

Instead of using a particular date, a day of the week can be specified using the following dates:

For example, to specify that travel should begin at 5:00 p.m. on Tuesday, specify the parameter value as 1/2/1900 5:00 PM.

Accumulators (optional)

A list of cost attributes to be accumulated during analysis. These accumulation attributes are purely for reference; the solver only uses the cost attribute specified by the Impedance Attribute parameter to calculate the route.

For each cost attribute that is accumulated, a Total_[Impedance] property is added to the routes that are output by the solver.

Use Hierarchy in Analysis (optional)

The parameter is disabled if a hierarchy attribute is not defined on the network dataset used to perform the analysis.

Output Path Shape (optional)

U-Turn Policy (optional)

The U-Turn policy at junctions. Allowing U-turns implies the solver can turn around at a junction and double back on the same street. Given that junctions represent street intersections and dead ends, different vehicles may be able to turn around at some junctions but not at others—it depends on whether the junction represents an intersection or dead end. To accommodate this, the U-turn policy parameter is implicitly specified by how many edges connect to the junction, which is known as junction valency.

7.    Impedance Cutoff (optional) قطع المعاوقة (اختياري)

يحدد قطع المعاوقة أقصى مقاومة يمكن عندها تخصيص نقطة طلب لمنشأة. يتم قياس أقصى مقاومة بواسطة المسار الأقل تكلفة على طول الشبكة. إذا كانت نقطة الطلب خارج الحد الأقصى ، يتم تركها غير مخصصة. يمكن استخدام هذه المنشأة لنمذجة أقصى مسافة يرغب الأشخاص في قطعها لزيارة متاجرك أو الحد الأقصى للوقت المسموح به لقسم مكافحة الحرائق للوصول إلى أي شخص في المجتمع.

تحتوي نقاط الطلب على خاصية Cutoff_ [Impedance] ، والتي ، إذا تم تعيينها ، تتجاوز خاصية Impedance Cutoff لطبقة التحليل. قد تجد أن الناس في المناطق الريفية على استعداد للسفر لمسافة تصل إلى 10 أميال للوصول إلى منشأة ، في حين أن سكان المدن على استعداد للسفر لمسافة تصل إلى ميلين فقط. يمكنك نمذجة هذا السلوك عن طريق تعيين قيمة قطع المعاوقة لطبقة التحليل على 10 وتعيين قيمة Cutoff_Miles لنقاط الطلب في المناطق الحضرية على 2.

تحتوي المنشآت على خاصية القدرة ، والتي إذا تم تعيينها على قيمة غير خالية ، فستتجاوز معلمة السعة الافتراضية لتلك المنشأة.

12. Start Time (optional) وقت البدء (اختياري)

Indicates the time and date of departure. The departure time can be from facilities or demand points, depending on whether travel is from demand to facility or facility to demand. 

يشير إلى وقت وتاريخ المغادرة. يمكن أن يكون وقت المغادرة من المرافق أو نقاط الطلب ، اعتمادًا على ما إذا كان السفر من طلب إلى منشأة أو منشأة إلى أخرى.
