SimplexLP vs Time Study Engineer

SimplexLP solves linear optimization problems, which can be mathematically described with an objective function and a set of constraints. With the new graphical representation (possible with 2 variables only) it is a lot easier to understand the theoretical concept of linear optimization! SimplexLP is the perfect learning companion for teachers (to set up problems) and students (to learn the Simplex algorithm). It is very easy to change coefficients and see how the solution varies. For the calculation the famous Simplex algorithm is used. With SimplexLP you can: – easily set up the objective function and the constraints; – solve maximization and minimization problems; – solve problems with unlimited number of variables and constraints; – solve problems with ≤, ≥ and = (in)equalities; – get all the possible solutions ("edges") to a problem; – get accurate calculations with fractions; – get your output in fractions or decimal values; – set a fixed value in the objective function, e.g. for fixed costs; – set the tab width (via a simple swipe gesture) to format the tableaus; – get a graphical representation of optimization problems with 2 variables. With SimplexLP linear optimization really makes fun!

Time Study is a practical time study app built for industrial engineers, lean practitioners, and production teams who need accurate cycle-time data on the shop floor. Conduct stopwatch-style time studies with a clean, focused interface designed for real work environments — not spreadsheets on a clipboard. KEY FEATURES • Precision timer — Uses wall-clock timing so your study stays accurate even when the phone is locked or you switch apps • Task-by-task capture — Record each element with start/stop timing as you move through the process • VA / NVA / NNVA classification — Tag every task as Value Added, Non-Value Added, or Necessary Non-Value Added • Multi-operator support — Account for more than one operator on a task • Save & review studies — Keep completed studies on your device and open them anytime • Export reports — Share professional PDF or Excel (CSV) reports via the iOS share sheet — save to Files, open in Excel, or email to your team • Analytics dashboard — See VA/NVA breakdown, cycle time summaries, and study-level insights across saved work • Background study mode — Minimize the app while the timer keeps running; tap the banner to jump back in • Built-in IE glossary — Quick reference for common industrial engineering terms • Designed for engineers — Created by an industrial engineer for factory productivity and time-motion analysis WHO IT'S FOR • Industrial engineers • Lean / Six Sigma practitioners • Production supervisors and team leads • Process improvement specialists • Students learning time study methods Whether you are balancing a line, documenting standard work, or analyzing waste in a process, Time Study helps you capture timing data quickly and turn it into shareable reports.
