Abstract In the complex financial environment, todays healthcare industry requires administrators who are familiar with efficient method of allocating scare resources. Many healthcare facilities have become similar to large business enterprises, which intend to achieve multiple and conflicting goals through integration and use of limited resources. The objective of this study was to develop the goal programming approach in the health-care field, and to determine the optimal sequence for treatment of surgical patients that maximizes the total contribution to profit.
Keywords Health-Care Services: Goal Programming.
Operational Research models in the field of health-care often involve parameters, which depend on the behavior of human beings.
Health authorities need information for planning patient services. Most of the information requirements of health authorities relate to the activities of patients and the consequent health service workload . In order to use this information in billing or budgeting services, these authorities need models to evaluate resource used by the patients and to estimate their future service need .
Arcangeli G. et al.  used multi objective model and discussed optimal adaptive control of treatment planning in radiation therapy. Blake et al.  have analyzed surgical process management conceptual framework in surgical services management. Blake et al.  developed the goal programming model to resource allocation in acute care hospitals. Problems of this type have quite often been investigated using Operational Research methods [8-16, 18], Lawrence et al. , Lee K.K.Y , Steffen Flessa , Vanda De Angelis et al. , have developed the multi-objective programming models for health-care planning and their areas of applications were adopted. In this paper we develop the goal-programming model, which determine the optimal sequence for treatment of surgical patients that maximizes the total contribution to profit.
There are many models, which are used in health-care [2, 6]. Goal Programming is one of the models in this context because it can describe the activities of individual goals. Goal
Programming is a mathematical technique and a variation of Linear Programming. Goal Programming is an approach that is capable of handling decision-making problems having multiple, conflicting goals. The objective function of a Goal Programming model can be composed of non-homogeneous units of measurement, and includes only the deviational variables (d and d+) that are complementary to each other.
The decision-makers goals may be ranked based on priority. Goals of equal priority may be weighted differently in order of quantifiable assigned values. Therefore, the objective of Goal Programming is to minimize the summation of deviational variables (i.e. the desired goal levels), subject to a set of goals and systems constraints.
DATA OF THE PROBLEM:
The data is collected from Care Hospital, Hyderabad. This is specialized in performing six types of surgeries: Urology, General, Orthopedic, Plastic, ENT and Neurology. The performance of these surgeries is constrained by three resources: Operating Room hours, PACU (Post Anesthesia Care Unit) hours and SICU (Surgical Intensive Care Unit) hours.
The required information is given in the following table.
Types of Surgical Patients
Capaci ty/Yea r
Operating Room (l1)
Average Profit (Rs)
Where Y1 = Number of Urology Surgery patients.
Y2= Number of General Surgery patients.
Y3 = Number of Orthopedic Surgery patients. Y4 = Number of Plastic Surgery patients.
Y5 = Number of ENT Surgery patients.
Y6 = Number of Neurology Surgery patients.
I1 = Idle hours of the Operating Room. I2 = Idle hours of the PACU.
I3 = Idle days of the SICU.

The goal-programming model developed is as follows: Minimize Z = P1 (d Â¯) + P2 (d Â¯) + P3 (d Â¯) + P4 (d Â¯)

The equations above however, require two slack variables, to allow the possible deviation above and below the goal achievement. Note that the d Â¯ appears in the objective function with a P1 coefficient. The reason is that, since first goal requires making at east Rs. 20, 25,000, there is no need to put any restriction on d +. The objective of the second, third and fourth goals are to minimize the idle capacities of all the scare resources. This is done by including under- achievement variables d Â¯, d Â¯ and d Â¯ in the objective function with priority coefficients P2, P3 and P4 respectively.
