  • a computer process typically includes an executing (running) program or portion of a program, current program values and state information, and the resources used by the operating system to manage the execution of the process.
  • a parent process may spawn other, child processes to help perform the overall functionality of the parent process. Because the parent process specifically spawns the child processes to perform a portion of the overall functionality of the parent process, the functions performed by child processes (and grandchild processes, etc.) may sometimes be described as being performed by the parent process.
  • a method 600 for managing a fleet of PMDs can be carried out using the system 400, where the PMD 100 as earlier described is utilised.
  • the method 600 enables the fleet of PMDs 100 to be deployed in an optimal manner.
  • the method 600 is performed at least in part using one or more electronic processing devices such as a suitably programmed microcontroller forming part of a PMD 100 and in communication with the central server 410, or the like.
  • a user utilises a mobile phone 430, possibly using a pertinent software application which is used to activate the PMD 100, and/or to transmit a request to the central server 410 for a PMD 100.
  • the request is transmitted via the communication network 420.
  • the request is received and processed at the central server 410.
  • the central server 410 would direct an assigned PMD 100 towards the desired location to fulfil the request transmitted by the mobile phone 430. Subsequently, at step 660, the central server 410 would direct a secondary PMD 100 towards the desired location of the user to avoid a shortfall of the PMD 100 at the desired location of the user.
  • a determination of the secondary PMD 100 can be similar to the process carried out in step 630.
  • the method 600 can be geo-fenced to avoid situations where users have to wait excessive durations for PMDs 100 to arrive at their location. This is because the speed of the PMDs 100 in the second unmanned mode is typically slow to avoid accidents or alarm with people around the unmanned PMDs 100.
  • the above described method 600 provides a number of advantages. Firstly, the method 600 minimises instances of PMD 100 shortage at a particular location, as there is a replacement mechanism in the method 600. Furthermore, the method 600 ensures that a PMD 100 can be delivered upon user request, which leads to conveniences for users. In addition, the method 600 ensures that PMDs 100 left in areas of low demand does not remain at the areas of low demand and will traverse to areas of higher demand, increasing utility of each PMD 100.
