INTRODUCTION

 

 

With the advent of computer technology and the internet ,consumers prefer to conduct their business electronically .These electronic transactions have to be monitored and carried out efficiently .There is a need to focus on the need and construction of negotiation protocols for e-commerce and also provide distance services through negotiation. Reo language can be used to construct these negotiation protocols as it provides formal semantics, offers dynamic reconfigurability and composability

 

In this project, the focus is on the construction of negotiation protocols using Reo language to demonstrate how it can help in solving the task of providing care to senior citizens in a minimum amount of time while maximizing work and utilizing the resources given effectively and how this system can be implemented using Java RMI and design patterns of Java.

 

This can be further described as:

Problem Definition:

• There are N Nurses trying to nurse S senior citizens located at L locations in T time slots.
• Schedules will have to be generated so that all Nurses will start the day and end the day from their location.
• Work Rule – All nurses will work on fixed regular day time.
• Work Rule - There is a max number of senior citizens nursed per day

 

Strategy:

• The senior citizens all need care at different or maybe at the same time and make requests for services.
• Nurses are allotted to provide care for them and one nurse maybe allotted to more than one patient/senior citizen.
• Some form of negotiation is needed to ensure that all senior citizens are attended to and given treatment without any delay using minimum number of nurses and within a short time span.

 

 

Bidding System Technique:

• All nurses interested in providing services to senior citizens will register with the bidding system specifying their contact information and their availability.
• Using the Bidding system, senior citizens can bid for nurse time.
• Senior citizens will be required to provide their contact information, type of care needed and the time they would like the nurse to visit them.
• Senior citizens need to give their priority number whenever they bid for nurse time.
• The priority numbers are stored in a queue.
• The bid validator checks to see which priority number is highest. The senior citizen with the highest priority is allocated the first nurse. The next nurse is allocated to the patient with the second highest priority and so on. Nurse1 may be allocated to more than one patient since the number of nurses is limited when compared to the number of patients.
• Once their request has been carried out the senior citizen’s bid request will be marked as completed(assigned a nurse) and he can place new bids for nurse time again.

 

The Reo Language is modified to provide this kind of scenario. A circuit detailing the sequence of events and how time slots are allotted to the senior citizens/patients is done in an effective manner. Reo’s circuit is so designed that any modifications can be made at run time if required. The basic idea is to maximize work or services given to senior citizens in a minimum amount of time using the resources effectively.
