A quantitative risk assessment system (QRAS) builds a risk model of a system for which risk of failure is being assessed, then analyzes the risk of the system corresponding to the risk model. The QRAS performs sensitivity analysis of the risk model by altering fundamental components and quantifications built into the risk model, then re-analyzes the risk of the system using the modifications. More particularly, the risk model is built by building a hierarchy, creating a mission timeline, quantifying failure modes, and building / editing event sequence diagrams. Multiplicities, dependencies, and redundancies of the system are included in the risk model. For analysis runs, a fixed baseline is first constructed and stored. This baseline contains the lowest level scenarios, preserved in event tree structure. The analysis runs, at any level of the hierarchy and below, access this baseline for risk quantitative computation as well as ranking of particular risks. A standalone Tool Box capability exists, allowing the user to store application programs within QRAS.

A task management system uses patient tags (e.g., wireless RFID, Infrared tracking, GPS etc.) for patient location tracking, together with an integrated workflow system to automatically, track patient location how long they have been there and how many patients are at the same location (e.g., waiting room) and manages waiting time and an overall waiting queue, supporting automated adjustment of healthcare staffing, patient flows, and team coordination. A task management system for use in providing healthcare to a patient includes a patient tracking processor and a workflow processor. The patient tracking processor automatically acquires data derived by wireless communication from patient attached tag devices for use in identifying a location of multiple patients in a healthcare enterprise and identifying a first number of patients at a particular location and a second number of patients awaiting receiving a particular type of treatment. The workflow processor automatically initiates a patient load balancing activity to improve a match between a healthcare resource and a patient load by communicating a message to update a healthcare worker task schedule with a task in response to a determination the identified first or second number of patients exceeds a predetermined threshold number.

The present invention describes mobile phone applications that include methods and systems which automatically schedule tasks from a dynamically-changing task list for efficient utilization of available time. Unlike the prior personal task scheduling systems, the proposed system uses optimization algorithms and computer programs when creating a time schedule of tasks. In order to schedule individual tasks, the system takes into account multiple constraints controllable by the user. Basic constraints include individual task's deadline, start-time, minimum and maximum time-chunks for task fragments, relative priority of tasks (in case of time-collision), etc. Further constraints may include user's general preferences regarding individual task or group of tasks. Specifically, preferences may include time-of-day (e.g., morning, evening), location (e.g., home, work, particular grocery store or chain, particular gym, park), etc. In order to schedule the tasks, the system considers the user's calendar information and regards scheduled time-slots in the calendar as unavailable time for task scheduling. The system also considers as unavailable user-defined time periods reserved for such activities as sleeping, eating, resting, etc., unless the task specifically involves such activities. Furthermore, the system is flexible in the sense that the user can choose not to follow the advised task schedule and reprioritize tasks at his / her will. The system contains other interactive features such as issuing various task alerts to the user, allows the user to decline / delegate tasks and visualization (e.g. based on color coding) of the task-list (based on the status of the tasks, for example, close to completion, cannot be delegated etc.). The allocation is adaptive, in that, the schedule is automatically updated as new tasks enter the system, after task completions, when task priorities are modified, and based on other user inputs such as task declining / delegation. Finally, the system can be operated in a networked mode in which joint tasks involving multiple users (and their calendars) can be scheduled. Since the system will store the calendared event times of each user in the server, a joint task among multiple users can be scheduled based on the superimposed calendars of the users while protecting privacy of individual user's calendars.

The invention provides a method and device for dynamically planning satellite emergency tasks. Before planning, time windows are screened between a satellite uploading point and ending time for the closest ground station time window before the completion time of emergency tasks to guarantee that the emergency tasks can be completed in time after an instruction is uploaded to a satellite and beforethe completion time, and during planning, when each task is inserted, it is necessary to check whether limit for the maximum storage quantity of the satellite is met or not. In this way, conflictionbetween task time windows and confliction between storage quantities of the tasks are considered, and the planned scheme is closer to the actual plan execution process of the satellite; during satellite execution, task completion means that task shooting data is already downloaded to a ground station, in this way, when the emergency tasks are inserted into the time windows for selection, a targetfunction, which means that the earlier the emergency tasks are completed, the better the effect is, is designed, and the strategy that subsequent downloading time windows are selected to be executed early as much as possible is designed.

The invention takes task complete time, fuel consumption and service priority as in-orbit service aircraft task scheduling optimization targets, establishes a mathematic model concerning to a multi-aircraft-task planning problem through designing decision variables and formalized constrain conditions, utilizes the improved NSGA-II algorithm for obtaining a Pareto optimal set of the problem and chooses a compromise scheme in the obtained multiple solution sets according to practical preference. According to the invention, the Pareto optimization set of the scheme can be obtained and then the optimal scheme can be selected when task time constraint, orbital transfer and maximum speed incremental constraint are met, so that the task optimization convergence speed is high and is more suitable for larger task models. The task planning problem is converted to a corresponding optimization problem for solving. The formed multi-target optimization algorithm is adopted and a condition that combined action of multiple targets cannot be taken into consideration comprehensively when the multi-target problem is converted to the single-target problem is relieved.

A computerized automated demand-based parts delivery management system and method is disclosed. Parts for use in a production facility are received at a warehouse and housed in storage inventory areas such as trailers parked in a yard. Data about the parts in storage inventory areas and their locations as well as an inventory of parts in the warehouse are stored in a database.

The operation further identifies storage inventory areas that have the needed parts. Process times for transporting parts between locations are considered in determining task times for transporting parts from storage inventory areas to delivery inventory areas so parts are replenished in advance of the deplete time determined by the demand pegging operation.
