This paper discusses variant categories of Late Request Customers (LRC) as they interpose with Early Request Customers (ERC) thereby resulting in Intermittent Vehicle Routing Problems (IVRP). We conceptualize the multiple priorities that arise in vehicle routing and the connectivity between priorities based on Time and Quantity as it affects the interjectory intermittent dynamical situations. Solving problems of this nature could be quite challenging. It requires optimization along different dimensions and directions. This is connected to the fact that uncertainties associated with real-life situations make life dynamic hence opening the vista that brought about intermittencies in Vehicle Routing Problems (IVRP).  To achieve these feats, this paper formulates a relation that fuses the various categories of LRC into existing ERC, analyses the fused LRC, and encapsulates priorities into the formulated relation. The formulated relation embraces a stochastic process introduced to the existing deterministic process, leading to dynamic situations in a typical VRP setting as they occur in real life.
