Abstract

A method which is of aid in the laying out of locations of personnel and equipments in functional organizations where the personnel and equipments do not exceed numeral 100 and can be represented as density units in rectangular or square lattices. The relationship among objects in a particular space can be accurately determined to minimize crowding. The method has utility in laying out military attack center items of equipments being operating upon by center personnel for purposes of enhancing man-machine interfaces throughout the attack center. The method of the invention may be used alone or in combination with other techniques such as multidimensional scaling (MDS) to improve the accuracy of such other techniques.

Claims

1. A method which aids in laying out spatial interrelationships among a plurality of objects including a predetermined number of items of equipment being operated upon by a predetermined number of people within a predetermined physical area, where said plurality of objects constitute a unitary functional organization, where said objects do not exceed 100 in number, and where functioning of said organization can be hindered by crowding, the method comprising the steps of:

(a) defining an initial configuration of said objects within said predetermined physical area;

(b) acting out a first scenario involving said objects within said predetermined physical area and recording movements of said predetermined number of people within said physical area performing at least one task, said recording step comprising photographing said movements of said predetermined number of people using time lapse photography;

(c) introducing information about said recorded movements of said predetermined number of people and said initial configuration into a computer;

(d) generating information on all possible locations of said predetermined number of people and said equipment in said predetermined physical area by constructing a finite number of experimental configurations of all said objects within said predetermined physical area with said computer;

(e) determining a first relationship between (I) the relative positioning of the objects within the predetermined physical area and (II)(i) a first distance among all possible pairs of the objects, (II)(ii) the number of objects, and (II) (iii) a magnitude of the predetermined physical area for said first scenario using said information from said time lapse photography and for all of said finite number of experimental configurations constructed by said computer;

(f) determining a minimum density measure among said predetermined number of people within said predetermined physical area;

(g) determining a maximum density measure among said predetermined number of people within said predetermined physical area; and

(h) selecting a set of relationships of said objects in said predetermined physical area wherein said first relationship for said selected set is at least equal to said minimum density measure and no more than said maximum density measure.

2. The method of claim 1 further comprising:

(i) adjusting the number of objects within said predetermined physical area;

(j) acting out a second scenario involving said adjusted number of objects and recording movements of people within said predetermined physical area using said time lapse photography; and

(k) repeating steps (c) through (g) when said method with said first scenario does not yield a first relationship which falls between said minimum density measure and said maximum density measure.

3. A method as set forth in claim 1

(l) wherein the relationship stated in step (e) varies (h) directly with the number of objects for a constant predetermined area;

(ii) indirectly with the predetermined physical area for a constant number of objects; and

(iii) indirectly with said distance among pairs for a constant number of objects and for a constant predetermined physical area.

4. A method as set forth in claim 1

(m) wherein the relationships stated in step (e) are defined as follows:

##EQU37## (n) where d_act is the average Euclidean distance among all possible pair of said objects, A is the predetermined physical area, and n is the number of the objects within the predetermined physical area.

5. The method of claim 1

(o) wherein the predetermined physical area represents an area within a submarine available for the location of a control center, said control center constituting a unitary functional organization for controlling at least one aspect of the submarine'"'"'s operation;

(p) wherein said predetermined number of people are crew members for said submarine and said predetermined number of items of equipment are located in said control center, each of said crew members having functional assignments in said control center in association with the operation of said items of equipment; and

(g) wherein said selecting step comprises selecting a set of relationships which yields a lay out for the control center having the items of equipment and the crew members positioned so that the crew members can carry out respective assigned functions in connection with said items of equipment with the least overall hinderance due to crowding within the control center.
