ETS is the emergency traffic light system. This traffic system will be building for the emergency cars such as ambulance, police and fire cars. On the other hand, the system will have minor and major complexities. Some of the complexities include programming the system, programming the systems will contain huge coding statements, which will present the system with major difficulties, which are also hard to manoeuvre. For example, to distinguish between the normal car and the emergency cars such as ambulance, the systems must select the right statement to let the emergency car pass in a safe way.
The emergency car also has the right of way compared with the normal cars and the coded statements in the programme should be programmed in such a way that there will not be any problem that may cause delays on them. The police cars also will have some privileges as the emergency cars and the system needs coding to reflect that. Coding will also contain the normal traffic light system process, which includes allowing for pedestrians to cross and the passenger service vehicles. The new trappings in the coding system may therefore affect the system by slowing its functions and lead to slow down in loading which may occasion undue delays (David, Cleland, Ireland, 2006, p.199).
Moreover, the server of the emergency traffic system should have a message structure that lets the main coding system recognize whether it is running properly or not. This will allow for detection of malfunction, system failure or breakdown altogether which may lead congestion when the right commands are not being executed for the traffic and road users to follow forthright. This kind of message structure will be complex to check out when coming up with the right plan by the emergency system designers. Another complexity is that catching a different car by the system will be a big problem besides the main tribulations, which usually face the normal lighting system; this problem might lead to congestion, traffic jams and in reality many car accidents, which was not the case before the introduction of the new system (Kerzner, 2010, p. 5).
The network used in the emergency traffic system is indeed a complex issue. Using the wireless system other than the main service providers may not connect accurately. Use of other service providers other than wireless has the advantage of ensuring right connectivity, as the signals are easy to detect in comparison to the wireless system of network. Wireless system of network might be cotted off because of the other signal network on the roads such as the telecommunication connectivity. Furthermore, building wireless connectivity to the point of having the right signals effect is quite complex.
The alternative to wireless connectivity is use of fibre optic kind of network connection. This will be more expensive and tough approach to go for. There are various factors considered in attaching the fibre optic cable option. One of the main factors is the landscape of the roads. The connection is depended on the landscape of the roads, and therefore setting up the ETS might be tough and a hard task on an inclined and disinclined infrastructure thus requiring very smooth and plain kind of terrain. Contrary to the assertion that the ETS system is an easy go in the market, advertising the ETS system might be tough and consequently difficult to sell in the market.
Not many companies will want to invest in such a venture, which is mistaken for a public good that the governments, non-governmental organizations or other well-wishers who function as non-profits can provide. Therefore, the organization will target the governments since they can be in a position to afford the system as compared to other stakeholders. On the other hand, emergency people will take the advantage of the system if the government goes on to install it, which presents another complexity. However, the governments may not be willing to accept the amount of money that the ETS goes for in the future (Kerzner, 2010, pp.15-38).
Complexity of Medical reminder system (MRS) project
Patients who are suffering of diabetes or blood pressure must take medication in time. Failure to adhere to the set prescriptions by the physician may lead to complications and thus the importance of taking medication in time cannot be over-emphasised. For instance, most people will care-less about their parents when they get old due to the new set of needs, which come with old age. At other times, people are going to disgust and ignore the routine of helping and serving patients. People will therefore consider the MRS as a reminder system model for old people and patients to remind them of what they are supposed to do at a particular set time.
That system concept somehow gets filler and at other times become very complex to the user. Therefore, for the user to identify that the MRS is out of order becomes a problem. When the system develops mechanical, technical or other problem it becomes risky for the user and more so if it goes to give the wrong timing for an activity due for execution. If the time is wrong, the patient may take the medication at a time not required by the doctor or physician or for the old person the time may not be right for breakfast, lunch, dinner, taking bath or going to sleep (David, Cleland, Ireland, 2006, pp. 40-85).
The complexity is therefore in trusting the medical reminder system, which at times may be faulty or develop a problem to continue reminding the patient to have the medicine on time. The concept of MRS needs to link with an emergency person at the same time just in case it fails to function well. The emergency person will also be able to monitor the MRS system and make sure that it is working at all times and at the same time ensure its commands are as per the settings. The networking system is also critical with the MRS device. The network for use by cell phone will be depending on the signals from a service provider. If the signal happens to be weak, the cell phone may fail to text the MRS equipment and thus the message will not reach the patient or the target person it is supposed to serve.
This reminder system is going to contain a massive coding for programming; therefore, debugging the system is complicated for the programmer to approve. For instance, if medicine is supposed to be taken after every six hours, then the coding in the MRS device will have to show exactly that and the programmer of the device has to also ensure it reads as such. This may be a very difficult task to do for the programmer and especially if he/she lacks the requisite experience in the field. These complications to the programmer translate to the user and so the whole system becomes hard for usage as it is bound to relay wrong and different information to a patient (Schenhar, 2007, pp. 205-276).
Controlling the timing system in the MRS is very complex. Occasioned by a situation where the timing is not regular and the system has to be set to reflect that condition. The programmer may not be able to do these irregular settings and therefore the system may fail to work. Therefore, the device will need an expert in the field of programming to ensure the finer details are captured in the settings and consequently ensure what is right and required is the information got by the patient. The MRS device will also be very expensive for an average household. The affordability issue will present those who will be interested with a complex decision to make. The organization which is the pioneer of the device will also incur a lot of expenses in doing the advertisements which may not have a lot of returns on their part and thus the need for market assessment which may take lots of resource (Schenhar, 2007, p.12).
