A movie theater is planning to offer the possibility to book the seats either online or at the kiosk of the theater. Design the booking application for the theater taking in account the following consideration:

- The theater has 100 seats only.

- More than one user may be trying to book the same seat at the same time.

- Any seat can be booked by only one user.

- A seat can be available for the kiosk agent and the online user at the same time but can be booked by only one of them.

- If the client did not book a seat online or changed his/her mind at the kiosk, the seat must be available again for booking.

Use the process synchronization techniques. You are allowed to use variables as much as you need in the design.

The code does not have to be complicated or detailed. Thanks for the help!

Perry plc is a large conglomerate company structured on a divisional basis. It seeks to maximise investor wealth. Head office avoids day to day involvement in divisional affairs and only intervenes if performance is considered unsatisfactory. Divisional performance is measured by residual income.

One of Perry’s larger divisions operates a chain of high-class hotels throughout the United Kingdom. The division’s mission statement is ‘To be the hotel of the first choice for business users and tourists’. Although the chain has generally been popular with tourists it is not proving quite so popular with business users and conference organisers. Competition in the top segment of the hotel market is fierce, with customers expecting the highest standards of facilities, service, and catering. Over the last two years, the division has invested a large amount of money in modernising its hotels including the improvement of bedrooms and public rooms, installation of gymnasia and swimming pools and the information technology features required by business travelers. A large amount of money has also been spent on staff training to improve service levels and on a television advertising campaign to promote improved hotels to business users.

Head office is concerned that the performance of the hotel chain appears to have declined over the last few years despite this expenditure.

         The following figures are available

The cost of capital applicable to the hotel division is 20% per annum

Required:

1. Calculate the residual income for the hotel chain for each of the three years.
2. Discuss three advantages and four disadvantages of residual income as a divisional performance measure.                                                                                                     ( 7 marks)
