The critical path method (CPM) is a project modelling algorithm developed in the 1950s for scheduling project activities, it is used to determine the critical path through the calculation of three parameters thus, slack, earliest event, latest event times for each activity.

K-Shortest Paths Q-Routing: A New QoS Routing Algorithm in Telecommunication Networks
Actually, various kinds of sources (such as voice, video, or data) with diverse traffic characteristics and Quality of Service Requirements (QoS), which are multiplexed at very high rates, leads to significant traffic problems such as packet losses, transmission delays, delay variations, etc, caused mainly by congestion in the networks.

Comparison of k-shortest paths and maximum flow routing for network facility restoration
In the development of technologies for span failure restoration, a question arises about the restoration rerouting characteristics to be specified. In theory, maximal rerouting capacity is obtained with a maximum flow (Max Flow) criterion. However, rerouting that realizes the k-successively shortest link disjoint paths (KSP) may be faster, easier, and,

Ak-SHORTEST PATHS ROUTING HEURISTIC FOR STOCHASTIC NETWORK EVACUATION MODELS
Stochastic-network evacuation models require an optimization process to determine the best evacuation routes for a building's occupants. The optimization process developed and applied below is a heuristic based on the K-th Shortest Path Algorithm.

Route Finder: Efficiently Finding k Shortest Paths Using Constraint Programming
In this paper, we describe a Constraint Programming (CP) route finding application for a container transportation company. Mathematically, this amounts to finding the k shortest paths in a directed graph. However the nature of the business constraints rule out known algorithms such as Dijkstra's.

Improved Route Selection Strategy Based on K Shortest Path
LEO satellite networks have many advantages, such as global coverage and short latency, which play a crucial role in the future global communications. Under the tide of the Internet of Things, LEO satellite networks, as an effective means of connecting remote regions, will become indispensable pillars in the integrated system of the Internet of Things.

For finding all-pairs shortest paths in a digraph of n nodes, the well-known Floyd-Warshall method yields a particular best path between each pair of nodes efficiently in running time O(n3) when there is no negative-cost cycle (and all ties are ignored). Such a digraph may be a model of a real-world transportation, communication, or road network; then,

Multi-tiers route design coordinating QoS-specific K shortest paths over optical network
In the Wavelength Division Multiplexing (WDM) based optical circuit switching network, it takes longer time to set up the intermediate optical cross-connecting devices on the route. Thus, pre-computed routing approaches are desirable to instantly set up the connection.

In communication networks, traffic carried over long paths suffers from a higher call blocking probability (CBP) than those carried over short paths. This is a well-known fairness problem. Such a problem becomes more serious in wavelength-routed optical networks (WRONs) due to the wavelength continuity constraint.
