  • Ticket #46 – Description

    initial v1  
    1515== Chemintro redesign impetus
    1616
    17 Data entry in Chemintro becomes, however, quite onerous for formulators who work with multiple blends of chemical mixtures in varying proportions.
     17Data entry in Chemintro becomes, however, quite onerous for formulators who work with multiple blends in varying proportions in different products.
    1818
    1919There is a Chemintro redesign impetus to ease data entry by using prepared blends of chemicals to formulate products directly instead of, or together with, individual chemicals.
    … …  
    2727* A blend needs to be selectable alongside chemicals in a product
    2828
    29 * Different blends may be selected for the same product
     29* Multiple different blends in varying proportions may be used in the same product
    3030
    3131* A blend must transform into a set of actual chemicals making up a product
    … …  
    3737* Main Menu section labelled ''Blends'' with ''Add a new Blend''
    3838
    39 * Enter a Blend name unique to that company
     39* Enter a Blend name
    4040
    41 * In a sub-section ''Add another chemical''
     41* In a sub-section ''Add another chemical'' select an existing Chemical - but not an existing Blend - as the new ingredient
    4242
    43 * Select an existing Chemical as the new ingredient
     43* Enter the ''Precise proportion'' of the Chemical in that Blend
    4444
    45 * Enter the ''Precise proportion'' in the blend
    46 
    47 * Repeat adding chemicals until the blend is complete (<= 100%)
     45* Repeat, adding chemicals until the Blend is complete (<= 100%) and [Save]
    4846
    4947== Product user interface
    … …  
    5149* Add or select a Product
    5250
    53 * Enter or update product related data
     51* Scroll down and click ''Add another Product-chemical proportions''
    5452
    55 * Scroll down and Add another ''Product-chemical proportions''
     53* Select blends before selecting chemicals because saving a Product with a Blend will automatically add all the chemicals in the blend at the correct proportions.
    5654
    57 * Select a Chemical or a blend, enter Precise proportion and Max concentration and [Save]
     55* Select additional chemicals as required. If one of the blend related chemicals needs to be "added" it will already be there so just increase its ''Proportion'' and adjust its ''Max concentration'' accordingly.
    5856
    59 == Result of entering a Blend
     57* On saving, any blends involved will be scanned and proportions of chemicals common to multiple involved blends will be summed ''pro rata'' per the Blend proportion in the Product. Likewise, max concentrations will be recalculated.
    6058
    61 If a Blend was saved with specific proportion and max concentration, it will add all the constituent chemicals and recalculate all chemical volumes.
    62 
    63 
     59* If the ingredient chemicals calculated proportions and max concentrations exceed the existing values it means one or more blends containing some of the same chemicals were added and so the larger values will be used to update those chemical proportions and max concentrations. Otherwise, a human must have manually increased the value - hence they will not be updated.
