This paper provides a method for designing uncluttered displays that contain the needed amounts of data.

The method develops displays from primary system requirements and includes a computer program (a rule-based system) that assigns hardware attributes (including gray scale, color, and area fill) to compo- nents of the picture (display ele- ments). The resultant display is data-intensive but not overwhelm- ingly complex. 11:00 am—"System Concept and Criteria for Battle Group Deci- sion Making," by David Abra- ham.

The command and control system problem associated with the battle group, an ad hoc assemblage of nav- al resources with the mission of achieving a predetermined objective as assigned by higher authority, is discussed. After restatement of the problem, criteria for evaluating sys- tem concepts are proposed, with emphasis placed on combat envi- ronments.

The paper presents a concept for development of a battle group com-

The phi- losophic principle is command by exception in a multihierarchical structure. Functional partition into warfare areas such as ASW, AAW, and ASUW provides the basis for the multiple branches of the hierar- chy.

Testing & Reliability

Moderator: Capt. James G. Bur- ritt, USN

Assistant: Bruce H. Barber 9:30 am—"Reliability of Ship- board Elevators—There Is Hope for

Improvement," by William C.

Compton, Theodore C. Ander- er, and Frederice A. Heinze.

The history of Navy cargo/weap- ons elevator installations reveals wide variety of equipment sizes and configurations developed by numer- ous vendors working to different performance specifications for each contract. The result has been poor reliability, a proliferation of spare parts requirements, and logistic and maintenance nightmares. To correct this, NAVSEA has initiated a pro- gram to develop and test improved, standardized designs. The improve- ments include standard capacities and speeds, lightweight construc- tion, and easy removability for maintenance. This is being accom- plished through standard drawings and detailed, as opposed to per- formance, specifications. But the key to the success of this effort is to design and test for reliability, main- tainability, and safety. 10:15 am—"Electronic Module

Design Evaluation by Thermal

Imaging Analysis," by Kip O. Hof- fer, Thomas W. Shaw, and Lar- ry D. Robertson.

Thermal imaging (thermography) is a noncontact measurement tech- nique that can determine the tem- perature of an object by measuring the amount of infrared radiation generated by the object. As it is a noncontact method of temperature measurement, thermal imaging is useful in almost any situation where the surfaces to be measured are in motion, electrically hot, changing temperature rapidly, or where a contact measurement would tend to upset a thermal balance.

This paper reviews the work being done at the Naval Weapons Support

Center in Crane, Ind., in the areas of thermal imaging and thermal design verification of electronic modules. 11:00 am—"Ship Systems Test

Some technical managers are moving closer to a more disciplined approach when introducing ship systems into the fleet. In the past, many systems were installed with inadequate testing. The conse- quences show in impaired perform- ance and system down-time.

Thorough, cohesive and well- managed testing will insure opera- tionally ready ship systems. Howev- er, the technical manager must con- sider testing as an integral process
