There's one other competitor hoving into view, of course: Apple with its iTunes Radio, which lacks an on-demand element, but will come preloaded with the second most popular smartphone and tablet ecosystem in the world, iOS.
"While people like the on-demand element of Exec, it's different with cleaning," Kan said.
However, the company has since pivoted slightly, and like others in the crowdsourced photography space, now positions itself as a reverse marketplace for stock and other types of timely photography, giving an on-demand element to the photos it sells.
However, with today's funding announcement, the company is emphasising new features that create what is essentially a reverse marketplace for stock and other types of timely photography, giving an on-demand element to the photos it sells.
(b) The average size of demand elements is set to D f)=Y/n(f) hours depending on f = 1, 3, 7 for the individual demand frequency scenarios.
External demand is given in the form of demand elements which are distinguished by product type, demand quantity and due date defined on a continuous time scale.
Since in our view conventional lot sizing and scheduling models do not sufficiently reflect the conditions given in industrial production systems we propose an alternate approach, called block planning, for scheduling production orders on a continuous time scale with demand elements being assigned to distinct delivery dates.
In block planning, for each demand element a due date is defined on a continuous time scale.
Assume that demand elements are consolidated on a daily basis.
With f representing the demand frequency factor for distinguishing between low, medium and high demand frequency, the average number of generated demand elements is determined as n(f) = N/f giving a total of n(1) = 3840, n(3) = 1280, and n(7) = 549 demand elements on average generated in the three demand frequency scenarios with f = 1, 3, and 7, respectively.
